The wireless mobile service with a high bit rate using CDMA-1X EVDO is now widely used in Korea. Mobile devices are also increasingly being used as the conventional communication mechanism. In this study, we have developed JPEG 2000 compression module. We have also developed a web-based mobile system that communicates patient images using CDMA-1X EVDO for emergency care. A wireless mobile emergency patient imaging communication system is developed by using Microsoft Visual Studio.NET, and JPEG 2000 ActiveX control for PDA phone was developed by using the Microsoft Embedded Visual C++. Also, the CDMA-1X EVDO is used for connections between mobile web server and the PDA phone, and between ambulance car and hospital. In particular, images were compressed into a JPEG2000 format and transmitted from the hospital to the radiologist using a PDA phone located outside of the hospital. We successfully demonstrated this system for moving using an RW-6100 PDA phone used in the Yonsei university medical center in Korea.
