Figure-1-homeSocial media has revolutionaized the mode of interaction with family and friends setting expectation to have update on your Facebook page every minute.  Yet another leap in the technology is growth of social media on mobile platforms, which is the future of social media as evident from $19 billion acquision of Whatsapp by Facebook.  

Healthcare community has seen activity in socail media area geared towards health and health issues.  Figure 1 is one such company started in Canada referred as instagram of doctors. Figure 1 raised $2 million of seed funding in December 2013 by a crowd-sourced community of physicians readily sharing medical images. Poor selectivity of medical imaging in Google images and expensive private medical image libraries motivated Dr. Joshua Landy, an Toronto-based Pulmonary/Critical Care specialist, to give birth to Figure 1.

What are main features of Figure 1, medical instagram?
Figure 1 is a free platform that offers physician verification (via personal registration or Doximity integration). Figure 1 allows:

  • Sharing of patient images by individual physicians
  • Patients can sign consent form that is individualized by clinic or a genernal form from Figure 1
  • Ability to  de-identify photos by allowing the uploading user to block out faces, tattoos, and distinguishing features of patients.figure1
  • Also developing browseable image categories  (by specialty or anatomy).
    • This provide easy access to the massive database topically
    • Users can suggest alternative categorizations (each image can be in multiple categories) to assist in future discovery of these images.
  • Retains a clean, simplified, but highly functional user interface.

What platforms are supported by Figure 1?
You can access Figure 1 through iPhone, Andriod app and through internet/ web. Andriod app and web browsing capability has been added within last week.  Image categorization has not been yet incorporated in Android platform, but the Figure 1 team expects the Android and iOS team to have feature parity over the next few months.

What is the current traffic on Figure 1?
Figure 1 is seeing steady users with over one million views per week and each image viewed thousands of times.  The uploads receive multiple comments, with many comment sections exceeding 5 posts.

What countries have access to Figure 1?
Figure 1′s is available internationally in Ireland, the UK, Australia, New Zealand, the USA, and Canada.

Furthermore, the Figure 1 team highlights a particularly interesting finding or case each week in their Image of the Week mailing list. Figure 1’s user experience is limited to search and viewing of images and is looking to expand this capability to provide users much more rich experience in near future.  KAH is excited by the platform created by Figure 1 and look forward for Figure 1 to be a part of Facebook family!

Oral-B-SmartSeries-Bluetooth-Electric-ToothbrushToothbrush has been a simple day to day gadget that is useful in keeping your teeth clean. Development of battery operated and further more recharageble toothbrush provided better users experience and more control on dental hygiene. Now we are entring a era of merger of information technology with medical devices, which is touted to give growth to the medical device sector. Beam technologies came out with first connected manual toothbrush in 2013, cleared by FDA in 2012 for $24.99.

Oral-B, one of the market leader in dental products made announcement of Bluetooth-connected electric toothbrush line, named SmartSeries to be available in iOS and Andriod this year.  The SmartSeries tooth Brush will be available to users in Germay and USA in June 2014.

How many modes does Oral-B SmartSeries toothbrush has?
The SmartSeries has six different brushing modes:

  • Daily cleaning
  • Deep clean
  • Whitening
  • Gum Care
  • Sensitive
  • Touge cleaning

Theese modes can be personalized by the user with help of their dentist.

How does Oral-B SmartSeries toothbrush help user?
SmartSeries app will start timing when you will start brushing with the selected brushing routine.  Also you will

  •  get alert message if too much pressure is applied
  • see graphical view of brushing performance over time

The app also suggests nearby dentists, and logs your appointments. It reminds you to replace your brush head every 90 days, with a link to buy more, and pictures to make sure you pick the right one.

“[Our Bluetooth connected toothbrush] provides the highest degree of user interaction to track your oral care habits to help improve your oral health, and we believe it will have significant impact on the future of personal oral care, providing data-based solutions for oral health, and making the relationship between dental professionals and patients a more collaborative one,” Wayne Randall, vice president of Global Oral Care at Procter and Gamble.

What is price tag on Oral-B SmartSeries toothbrush?
The toothbrush is set to launch with price tag of £199 in the UK, or 219 euros in the rest of Europe, and £219 in the US.

Is Oral-B first company to launch connected toothbrush?
Oral-B is the first big company to launch connected toothbrush, but not the first in this space.  Two other companies have connected toothbrush in market

  • Beam Brush – manual toothbrush launch in 2013, FDA approved in 2012
  • Kolibree – Launched electric brush in 2014.  The detects whether you hit all hard to reach places between gums and teeth along with brushing time

 The connected toothbrush does look like a promishing technology, but how much will you pay for such a toothbrush?  Also, with everything connected to internet, it will be interesting to see, how much of the data is analyzed by the user or clinic and put to use to further refine medecial care such as dental hygiene.  Dental hygiene is definetly important, but is connected bluetooth brush from companies like Oral-B an overkill?

Vital signs are measures of various physiological statistics, often taken by health professionals, in order to assess the most basic body functions. The act of taking vital signs normally includes recording body temperature, pulse rate (or heart rate), blood pressure and respiratory rate, but may also include other measurements. Smartphones are becoming popular devices for to capture these vital signs.

One more vital parameter to be measured and monitored is the oxygen saturation of a patient’s blood  i.e. patient’s oxygenation. A blood-oxygen monitor, pulse oximeter displays the percentage of arterial hemoglobin in the oxyhemoglobin configuration.

Physiological parameter monitoring with a smart phone
A researcher from Worcester Polytechnic Institute has developed a smart phone app that measures not only heart rate, but also heart rhythm, respiration rate and blood oxygen saturation using the phone’s built-in video camera.

The app analyzes video clips recorded while the patient’s fingertip is pressed against the lens of the camera. Just like a standard clinical pulse oximeter, it then captures small changes in light reflected by the pulsing blood in the capillaries, and translates these changes to the actual vital signs by using the same algorithms employed in professional devices.

The results show that the smart phone monitor was as accurate as the traditional devices. When professionally launched, this could become a powerful diagnostic tool which is readily available to both doctors and patients anywhere they are.

Further,  they are working on an app for accurate detection of atrial fibrillation from the heart rhythm signal and have started a preliminary clinical study. I think the development of iPhone apps is going in the right direction by making iPhone as “all in one” portable communication as well as basic health diagnosis tool.

Apple release of iPhone 4S has created excitement among the smart phone users. Apple fans queued up in front of Apple store, some dressed as Steve Jobs, dedicated the 4S to Steve Jobs referring it as “for Steve”. Along with iPhone 4S, Apple released iOS 5 for the iPhoneiPad and iPod Touch which has added features. However, there is one new feature, which brings body area network technologies to the consumers is Bluetooth 4.0 with Apple being the first consumer device maker to begin embedding Bluetooth 4.0 in their products.

Medical Applications
With the latest software from the iOS line touting over 200 new features, Apple has created a viable consumer base for developers of applications in the largely unexplored realm of body computing and wearable sensor networks. By embedding Bluetooth 4.0 i.e. BLE in their iPhone, 4S device will prove to be a huge stimulus for developers of emerging mobile health devices incorporating low energy technology.

Bluetooth 4.0 enabled devices are backwards compatible, thus BLE will not be replacing the existing Bluetooth protocol used for most wireless interaction on mobile devices for higher latency activity. “Closed Bluetooth”, “Bluetooth High speed”, and “Bluetooth Low Energy” in one unique feature. Moreover, set up time is < 3ms and power consumption is < 15mA.

Potential to revolutionize health care devices
Bluetooth technology allows devices to communicate and transfer key information wirelessly. Bluetooth 4.0 standard contains many vital features that will certainly increase adoption of the standard among medical device manufacturers like bluetooth devices to maintain power for weeks to months without a charge.

MICU or NICU, or any other ICU unit, will be without a jumble of wires connected to the patients. Instead, they will have small bluetooth sensors attached to them, synced wirelessly to display monitors next to them.

Transporting patients to imaging rooms and other locations would not be required, cutting down the risk of bacterial infections from the lengthy wires with no risk of people tripping on wires.  These are just a few of the potential benefits.

The Bluetooth Special Interest Group (SIG), a consortium of industry supporters responsible for developing the standard, was mandated to build a standard to incorporate use of medical devices, since device to device communication is an everyday occurrence in hospitals and doctors’ offices. The specification is now complete with 30-40 vendors already qualified to support it, with the following critically useful features:

1-Integration The Health Device Profile
The recently released Health Device Profile (HDP) is specifically tailored for medical applications by incorporating IEEE standards for their medical devices (e.g. pulse-ox, glucose meters, etc), which allow  transition their device connectivity easily onto the Bluetooth HDP. The HDP allows  standardization of the data format, increasing interoperability, leading to a flourishing market of health related devices using wireless communication.

2-Bluetooth advantages- cost and power consumption
While Wi-Fi connectivity is ubiquitous throughout hospitals and now most offices, the power needed to maintain a wi-fi connection precludes its use in tiny medical devices with minimal capacity for battery storage. More expensive devices, such as cell phones, can afford to maintain a cellular connection, such as 3G or EDGE, but this cost would prevent widespread adoption in small, potentially disposable medical devices.

3-Manager devices
The vision of HDP is that a nearby manager device (“sink”) would be responsible for aggregating and transmitting information collected from one or more Bluetooth devices. Thus, a device by the bedside could collect information from multiple patient sensors and transmit it over the hospital Wi-FI network to doctors and nurses. A nearby mobile device, such as a smartphone, would be the aggregating device and a continuous reading of, say, movement (i.e. exercise) or heart rhythm data, could be collected and forwarded to the cloud for review by the physician.

Continuous improvement in features that being integrated in smartphones with iPhone 4s leading the way will definitely enhance the adaptability of the technology for medical or healthcare applications.

Ultrasound-based diagnostic imaging technique used for visualizing subcutaneous body structures including tendons, muscles, joints, vessels and internal organs for possible pathology or lesions. Obstetric sonography is commonly used during pregnancy and is widely recognized by the public. MobiSante show cased its mobile based ultrasound device in Mobile Health Expo in late 2010. Food and Drug Administration (FDA) approved its ultrasound gadget named MobiUS SP1.

Ultrasound Machine
An ultrasound machine is a medical equipment that uses probes that go either in the body or on the surface, and in the case of pregnancy, is used to get a clear picture of the fetus and its development in the womb. The frequencies used in diagnostic ultrasound typically between 2 and 18 MHz.

Smartphone-based ultrasound imaging system
MobiSante has launched smartphone-based ultrasound imaging system, MobiUS™ SP1. It has been cleared by the FDA, brings ultrasound imaging within reach of health care professionals everywhere at reduce costs.

It works on Windows Mobile 6.5-based Toshiba TG01 smartphone. Smartphone’s cellular and Wi-Fi connections can be used for sending images for consultation or storage in the PACS system, making it easy to keep a record of all images for reimbursements as well as benchmarking.

Other benefits

  • A rural OB/GYN can confirm pregnancy and detect common complications without sending patients to the centers.
  • GP can look for gall bladder, kidney stones and aneurysms while they are conducting regular physical exams of their patients.
  • Qualified Emergency Responders can use such devices to do simple diagnosis at the site of an accident.

Enhanced access to ultrasound imaging may create a bigger demand for the expertise of Radiologists back at the main healthcare center, reducing costs by enabling earlier and faster diagnosis. The recent trend has been development of handheld ultrasound machines by Giants like Philips, Toshiba, Siemens, etc to capture rural market of developing countries like India and China.  Device developed by MobiSante falls in the same realm and shows promise to be used as basic diagnostic tool at low cost.

A microscope is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope. Researchers from university of California, utilized iPhone as microscope and spectrometer. California Institute of Technology researchers transformed iPhone or smartphone into imaging platform to study cultures or described as ePetri dish.

Microscopy has been used to reveal details about anatomy and physiology. An example of this is in elucidating the various kinds of blood cells; white blood cells or leukocytes especially. Blood cell counts, in which a lab worker will smear a film of blood on a slide, stain it and examine the specimen under the microscope, have become a prime need in modern medicine. The relative numbers of the different types of leukocytes are of diagnostic value.

The structure of the cell can be studied through the lenses of a microscope. This has led to progress in modern medicine and biology in a wide range of sub-disciplines. Microbiology has become a discipline by itself.

Smartphone-Based  lens-free microscopy
Engineers from the California Institute of Technology (CalTech) have devised a ePetri dish: a small, lens-free microscopy imaging platform.  The prototype was built using a smartphone, a commercially available cell-phone image sensor and Lego building blocks, instead of using a large, heavy instrument, for providing high-quality images of cells.

The culture is placed on an image sensor chip and the phone’s LED screen functions as a scanning light source. The ePetri device is then placed in an incubator, with the image sensor chip connected to a laptop outside the incubator through a cable. The image-sensor takes pictures of the culture, the data is sent to the laptop and so cultures can be monitored as they grow. The technique is apparently particularly useful in the imaging of cells that grow very close to one another. The ePetri is able to monitor the entire field, but can still zoom in on areas of interest within the culture.

Likely deployment of ePetri
The research team sees many possibilities  the deployment of ePetri, such as drug screening and detection of toxic compounds. It could even provide microscopy-imaging capabilities for other portable diagnostic lab-on-a-chip tools. The team is also working on a more comprehensive system that would include a small incubator, transforming the ePetri into a desktop diagnostic tool.

Scientific community has been actively looking into exploiting iPhones and other smartphone as diagnostic tools by adding peripheral kits.  Future entails more development along these line and we look forward to these.

Steve Jobs founder of Apple died yesterday, which has created a wave of sadness around the world.  Steve job’s vision was key in developing and launching iPod, iPhone and iPad. KAH team would like to pay homage to Steve Jobs and legacy of innovative products he has given to the world.

There were speculations of release of iPhone 5, but Apple launched iPhone 4S, which looks similar to iPhone 4 with some internal advancements. Apple has integrated following features in iPhone 4S:

  • Faster A4 processor, better batteries, bigger 64GB of storage
  • Dual antenna to reach 4G speed with power drian
  • 8 MP camera having capability to capture 1080p HD video with “real-time video image stabilization.”
  • Siri personal iPhone assistant , turns your iPhone into an interactive computer you can talk to.
  • iCloud launching on 12 Oct, which allows your music, photos, apps, contacts and pretty much everything else exists in one place competing with Amazon and Google.

Wonderful deployment of iPhone 4S
Researchers from the University of California can utilize iPhone 4S as high-quality medical imaging and chemical detection devices. By adding some hardware and maximising the capability of the iPhone, they were able to transform it into a microscopy and spectroscopy tool. The microscope feature is being validated and the researchers plan to improve the basic concept as well, like using other lenses and different software to make it useful for different applications in a variety of clinical cases. The spectrometer is still in its early stages

Microscope Feature
Using 5x magnification ball lenses (1 millimeter-diameter) and the high resolution of the camera’s semiconductor sensor, the iPhone microscope could distinguish features on the order of 1.5 microns. This is small enough to see different types of blood cells. To obtain a good image, the researchers had to use digital image processing software to correct for distortion caused by the ball lenses. The images are not as sharp as those obtained with commercially available lab microscopes, but they can be of use where regular microscopes are not available. The team used ball lenses i.e. finely ground glass spheres that act as low-powered magnifying glasses. The team used a 1-millimeter-diameter ball lens that costs $30-40 USD in their prototype, but mass-produced lenses could be substituted to reduce the price.

To build the microscope’s lens, Kaiqin Chu, a post-doctoral researcher in optics, inserted a ball lens into a hole in a rubber sheet, then simply taped the sheet over the smartphone’s camera.

Spectrometer Feature
Spectrometers smear out light from an object, separating it into its composite wavelengths in much the way a prism breaks up white light in the familiar colors of the rainbow. Since atoms and molecules absorb very specific wavelengths when exposed to light, it is possible to tease out the chemical signature of materials by studying their spectra.

Like the microscope, the iPhone’s spectrometer takes advantage of smartphone imaging capabilities.

To make the spectrometer, the researchers used plastic tubes covered with black tape, in which they made a narrow slit. This way only parallel beams of light are captured. With the spectrometer feature they plan to measure quantities of oxygen in the blood and provide help spotting chemical markers of diseases.

The microscope feature is being validated and the researchers plan to improve the basic concept as well, like using other lenses and different software to make it useful for different applications in a variety of clinical cases. The spectrometer is still in its early stages.

The iPhone is being transformed into a diagnostic tool, which would become very handy for developing countries, wherein diagnostic tool may not be available in remote areas.  We are excited about the recent developments and look forward for more advancements.

Presbyopia is a condition in which the lens of the eye becomes progressively unable to focus on objects close to the viewer. The condition is a normal part of the aging process. The most common treatment for those suffering from presbyopia is corrective lenses, either eyeglasses or contacts either reading glasses or bifocals. Even the most common type of eye surgery, LASIK, is not effective for the treatment of this. An iPhone app addresses presbyopia by stimulating the visual cortex.

iPhone based application
, a U.S. company based in Israel, has developed their application called “Glassesof”. This iPhone based application can help the patients with presbyopia to see up close. This application is developed to boost visual acuity by using a proprietary method that affects the brain’s visual cortex performance for a longer period of time.

Principle of application
Similar to computers binary code, everything captured by the human eye is translated into digital binary form i.e. “0” and “1” by the vision system in the brain. Those “0” and “1” are translated into visual images such as Gabor patches that vary by their spatial frequency, contrast and spatial orientation and  stimulate the neurons in the early visual cortex of the brain.

“GlassesOff™ application enhances the visual system’s image processing capabilities by using the optimal Gabor patches to stimulate the visual cortex. The treatment significantly boosts the speed and quality of image processing in the brain. On average, the patient is required to be trained 3 times per week, each  lasting for a 15 min, a total for 3 months. Once eliminating the need for reading glasses,  maintenance training protocol is required for 2-3 treatment session per month.”

Ucansi, has termed the method  as “using the brain as glasses”. They have further indicated that the application will cost about $95 and will become available early next year.

Health apps developed for medical professionals have gained momentum with  MIM mobile radiology imaging app setting stage by getting FDA approval.   ResolutionMD Mobile is another medical imaging app that got FDA approval last week.  Calgary Scientific developed this next-generation mobile app that delivers full-functionality advanced visualization of 2D and 3D, CT and MR images directly to mobile devices.

DICOM images and confidential patient information are stored in a secured server location and never transferred to iOS devices. This means clinicians get instant and secure access to the images they need.

Why choose Resolution Mobile?
Mobile medical image solutions require expensive proprietary hardware or transmission of images to the device for viewing. Resolution Mobile runs on off-the-shelf graphics and server hardware available from the major OEM providers. A supported mobile device with an installed client application connects to the Resolution Mobile server accessible via a wireless connection. The confidential patient information is never retained on the mobile device . This solution provides numerous benefits including:

  • Elimination of security concerns (information stays on the server )
  • Instantaneous access to patient data
  • Reduced IT infrastructure costs through elimination of redundant storage and centralization of installation and maintenance

Unique Network Rendering Technology
Its advanced, secure and centralized architecture does not require image data or confidential patient information to be retained on the mobile device, providing clinicians instant access and eliminating data security concerns.

Support Devices
Resolution Mobile currently provides support for Apple iPhone 4 and iPad 2, with the client application available via the Apple iTunes App Store. Future versions of ResolutionMD Mobile will provide support for other industry-leading platforms including Android.

Calgary Scientific ResolutionMD cleared by FDA
Calgary Scientific has received FDA clearance for its ResolutionMD Mobile radiological image browsing app (and underlying server system) for iOS devices of Apple i. e. iPads and iPhones. Fast image access and rendering relies on servers that prepare data to be used specifically by the app.

There is also an Android version of the ResolutionMD Mobile app, but that is being processed for FDA clearance.

  • It supports imaging modalities like CT, MR, SC, Enhanced MR, XA, CR/DR, PET and NM.
  • 2D: Dynamic window/level, Viewing presets
  • 3D:  Fully-interactive navigation, Free volume rotation & zooming,  Dynamic volume rendering & standard preset library, MIP/MPR,  Instant access to orthogonal orientations, Thick slab viewing (up to 50mm)
  • It has powerful work tools and auto-generated list of recent studies and DICOM query/retrieve access to PACS
  • It has universal access as it can operate on Wi-Fi and Cellular data networks (3G/4G).

The medical imaging app industry is moving in the right direction by getting FDA clearance.  ResolutionMD or MIM medical imaging apps would make diagnosis easier around the globe, wherein any physician available around the world can analyze the image.  Look forward for more advancements in this field.

Healthy imaging!

Smartphones have change the way phones are used.  You can perform e-mail messaging, web browsing, even reading and editing of Word and Excel files on the go with smartphones. While many other phones have similar functions, smartphones can offer users a bigger screen and a full keyboard, making data functions easier to use. These can also carry out synchronization of information with desktop or laptop computers. Smartphones are constantly evolving with increased functionality and NIT DOCOMO is looking to measure radiation, detect bad breath or determine your body fat via smartphone.

Radiation is a process in which energetic particles or energy or waves travel through a medium or space. There are two distinct types of radiation; ionizing radiation  (i.e., having sufficient energy to ionize an atom), and non-ionizing radiation (e.g., radio waves, heat or visible light). The energy radiates (i.e., travels outward in straight lines in all directions) from its source. Both ionizing and non-ionizing radiation can be harmful to organisms and can result in changes to the natural environment.

Ionizing radiation comes from radioactive materials, X-ray tubes, particle accelerators, and is present in the environment. It is invisible and not directly detectable by human senses

The non-ionizing portion of electromagnetic radiation consists of electromagnetic waves including radio waves, microwaves, infrared light.

The Innovative Smartphone
NTT DOCOMO , Japan’s leading mobile phone company is planning to unveil a smartphone equipped with different sensors and softwares to facilitate the user to measure radiation levels in their surroundings, or tells them if they have bad breath, or how much body fat they have.

It will be exhibited at Combined Exhibition of Advanced Technologies (CEATEC) JAPAN 2011, Japan’s largest mobile industry trade show, which will be near Tokyo from 4 to 8 October.

The company told that customers have been worried due to radiation since the Great East Japan Earthquake and they had been thinking of ways to address these customer needs as a telecom carrier.

The nuclear accident occurred at the Fukushima power plant, which is still leaking radiation and demand for radiation detectors has soared in Japan.

The company has also planned to provide a jacket that can tell if the owner smells of alcohol or is being exposed to UV light that might harm the skin.

Another version gives a reading of acetone in the breath. When the user blows into a device connected to the smartphone, it will tell  them, how hungry they are or when they are burning fat.
