Abstract

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 an emergency worklist system, JPEG 2000 compression module, integrated viewer for emergency medical information, and mobile web PACS. We have also developed a web based mobile system that communicates between patient information and images, using CDMA- 1X EVDO for emergency diagnosis. It is composed of a mobile web application system using the Microsoft Windows 2003 server and an internet information service. A mobile web PACS used for a database managing patient information and images was developed by using Microsoft access 2003. A wireless mobile emergency patient information and 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. This system allows fast access to the patient information database, storing both medical images and patient information anytime and anywhere. In particular, images were compressed into a JPEG2000 format and transmitted from a mobile web PACS within the hospital to the radiologist using a PDA phone located outside of the hospital. This system also shows radiological images as well as physiological signal data, including blood pressure, vital signs, and etc, in the web browser of the PDA phone so that radiologists can diagnose more effectively. We successfully demonstrated this system using an RW-6100 PDA phone used in the Yonsei university medical center in Korea.
