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 ActiveX 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 sysem are usablity 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.
