Collaborative Visualization and Annotations of DICOM Images for Real-Time Web-based Telemedicine System

Nowadays, E-health is increasingly used to offer applications that respond to the healthcare professionals’ problems and improve the services provided to their patients. In this work we focus on the visualization and manipulation of medical images by several physicians within the framework of a tele-expertise service. Indeed, such a service allows a local physician to share his patient's medical data with one or more remote medical experts in order to get a second medical opinion to better diagnose and/or treat the patient. The proposed solution in this paper allows collaborative visualization of medical images based on the DICOM standard via a web viewer, the annotations added by the remote physician are synchronized in real-time using WebRTC protocol, allowing a common display for all physicians participating in the tele-expertise session.
