Abstract :
In this paper, the prototype of the tele-ultrasound consultation system has been designed and evaluated over digital subscriber lines including ADSL and VDSL. The Active X control, and software-based MPEG-4 and H.320 CODECs (coder and decoder) allowed low-cost, flexible, Web-based, and real-time implementation for interactive teleconsultation through general Web browser. Specifically, the features of designed system are usability of the MPEG-4 coding of full-resolution ultrasound video, accessibility via Web browser, combined transmission of ultrasound video with video conferencing in real-time, and operability over cheap ADSL, and VDSL lines. The quality of ultrasound images in terms of compression ratio and frame rate were measured using patients´ data to evaluate the performance of the designed system over DSL lines, and to demonstrate usability for practical use.
