Paper Abstract

With the novel advances in wireless communication and personal mobile handheld devices, a newly emerging technology of medical visualization on mobile handheld is believed to provide advance service for physicians, especially in image-based diagnosis. In this paper, we have implemented an easy-to-use medical visualization system on mobile handheld device through WLAN. The system provides physicians a very convenient way to interactively access image data using their Pocket PC without the restriction of staying in the fixed location. System architecture, technical problems and solutions are discussed. Because of the huge gap between image server and Pocket PC client on processing power, the Pocket PC client used only for display image and interaction editor to change visualization parameters. Most render tasks are moved to the server. Since the wireless bandwidth is limited, we adopted a simple image compression scheme to achieve best trade-off between computational complexity and compression efficiency. A RS code is employed for forward error coding on UDP socket connection. Experimental results are clear enough to show this system to be practical for clinic diagnosis. The frame rate for lossless 256x256 24 bits color images transmission could reach 5 fps under 802.11b. We believe the system will provide advance service for the doctors.
