Sir,

This letter is a logical continuation of the earlier article by the author[1] wherein a locally-developed image viewer system, especially for medical diagnostic use, was diagrammatically illustrated. Since then, the author got possession of an Android OS-based Samsung Galaxy S5 Smartphone, which serves as an add-on device to this system. It is felt that this item, though mentioned briefly in the earlier article, deserves a detailed description/discussion in view of its several advantages for medical imaging and applications for medical professionals. Smartphones are useful for medical professionals as a handy device to store, display and receive/transmit gigabyte size images from multi-modalities across the entire globe and have been thus widely applied in teleradiology.[2],[3],[4],[5],[6] They have advantages such as: Ubiquitous hands-on access to patient data at any site, e.g., at the point-of-care basis; consultation among tumor board/class members or with peers for difficult cases and over reads, away from work stations; reduction of image distribution delays and enhancing physician and patient interaction. The same Wi-Fi broadband along with a mobile data net connection provided by Mahanagar Telephone Nigam Limited (MTNL, Mumbai) has been employed by the author for receiving/transmitting images. From the point of view of the radiologists, the important advantages of this smartphone are: 16/32 GB storage, 12.9 cm (5.1 inches) Full HD Super active matrix organic light emitting diode capacitive touch screen display (1920 × 1080 pixels, 432 ppi pixel density), high resolution digital camera (16MP, 5312 × 2988 pixels), card slot for micro SD (up to 128GB), 2GB RAM, sensors (accelerometer, gyro, proximity, compass, barometer, air gesture, heart rate), flashlight use, good battery life (talk time: 21 h), cloud facility, etc. The mobile communication network and Wi-Fi broadband may be used for sending/receiving SMS and E-mail messages, respectively. The manifold uses for doctors and technical features of this smartphone can be extracted from the manufacturer's user manual. The author has purchased a Samsung HDTV adapter which enables connection of the Galaxy phone to the Samsung TV earlier described. The TV feature is extremely useful for teaching and training students and radiologists. The author has tested the smartphone display for several JPEG and similar medical pictures/videos (converted from DICOM images) from various modalities and test patterns (AAPM, SMPTE) and in each case, the picture was crisp and clear, permitting correct interpretation, in view of its better display resolution. It may be noted that images may be opened in "abPhoto," "Gallery," "Photos," "video player," "UC browser," etc., Since the resolution of the Samsung smartphone is better than that of Samsung TV (1360 × 768 pixels) used by the author, all the images are also displayed faithfully on the TV. The light photography using the camera will be highly useful for clinical practices and studies, video conferencing and radiation protection education applications. Besides the regular phone and messaging applications, the Galaxy has other features. e.g., audio and video recording, Google maps, dictionary, grammar book, and internet access to hundreds of educational websites "anytime, anywhere," e.g. medical books, encyclopedia, etc., Access to social networks like Facebook, LinkedIn, WhatsApp, Twitter, etc., will be beneficial for radiologists for improving their contacts through cross-platform messaging, chatting, discovering new connections, posing questions and sharing expertise. The application of YouTube needs greater emphasis due to availability of a wealth of medical information through audio/video presentations. Care should be exercised when one uses Wi-Fi and mobile data network simultaneously. The use of mobile networks (2G, 3G, and 4G) is very expensive as compared to Wi-Fi and should be turned off during normal use. They should be used sparingly only when Wi-Fi is not functional or when outdoor use of the phone is necessary (Wi-Fi has limited range). The author has selected the broadband, DSL-550 (unlimited plan, with a quoted speed of 2Mb/s) of MTNL, available at a nominal monthly charge. This with router and modem is ideal for home use. It may be stressed once again here, though, that smartphones are not intended to replace full workstations. Furthermore, so far, there are only a few studies investigating the diagnostic accuracy/interpretation of medical images using smartphones.

Besides the MIM software, the author has successfully used three other commercially available popular software (the Swiss OSIRIX,[7] Canadian Resolution MD[8] and the German Aycan[9]) with Demo images; and DICOM (Radiant[10] and MicroDicom[11]) viewers, for medical image viewing and analysis. Thefirst software is meant for use with Apple iOS devices/Mac computers only; the second, with Android and Apple iOS devices and the third, with Apple iPad2/3. All these are almost fully approved by FDA. The DICOM viewers enable quick display, processing and measurements on the Acer ultrabook and were evaluated with sample images from various modalities (including the ones with animation features) downloaded from websites or imported from CD/DVD's. It may be pointed out here that each of the above software/DICOM viewers has its own unique features and utilities.
