In telemedicine, real-time processing, processing without distortion, and browsing without plug-ins for medical image are these reasons that hinder implementation of medical image teleconsultation system. The paper presents a design of medical image teleconsultation system. The system is designed and achieved by comprehensive adoption of Silverlight, Deep Zoom, WCF and image processing technology. During the course of teleconsultation, real-time interaction, sharing and browsing for medical image meet the requirement for patients’ image information processing. Based on B/S, the system can achieve accurate locating, high-fidelity reduction and enlargement and quick browsing for medical image, and real-time interaction for consultation information through a universal browser.
