Medical Imaging Viewer Application

This is a web-based practice management application developed for Android tablets. It includes case studies of patients in DICOM (Digital Imaging and Communications in Medicine) format. DICOM is a standard for handling, storing, printing and transmitting information in medical imaging. It includes a file format definition and a network. DICOM files can be exchanged between two entities that are capable of receiving image and patient data in the said format. All DICOM images need to be securely exchanged over network. Radiologists, clinicians can view patient’s x-rays on their tablet even if they are away from their clinic, sitting at home and if patients are unable to visit the clinics for some reason.

We created scrollable dynamic tree view for patient studies- tree view including patient’s metadata and thumbnail image for particular study. All features control was centrally implemented for selected patient’s X-Ray images. Using handlers, we implemented multithreaded environment very efficiently. We created very simplified MVC architecture and workflow-based mechanism, which could be used to handle single to multi-patient’s metadata and X-Ray images.

XML files, DB files were used to store patients’ metadata and X-Ray images were used to develop study tree of particular patient. AndroidManifest xml file was used to access different permissions and writing to external storage. Shared preferences were used to save user credentials as key value pair.

Android XML screen layout to show different search results and custom dialog layouts to show status and notification for particular request process were also developed. Custom dynamic tree view for showing patient’s study details with thumbnail images and custom views such as window leveling and zooming features were implemented as well
