Consulting with radiologists outside the hospital by using Java.
A Java-based teleradiology system that makes use of the Internet has been developed. Using this system, an on-call, off-duty radiologist can make diagnoses and perform consultations easily by reviewing the transferred images at home. The image accessibility of the system allows a hospital with such a system to assist an affiliated rural hospital without a full-time radiologist. The system consists of three components: the image server subsystem, the database server subsystem, and the client subsystem. All client subsystems of the system are designed to be symmetric. Users may retrieve images, manipulate them, and perform remote consultations. In addition, a user may add annotations to an image area of interest. Screen synchronization is achieved by means of the command-passing technique and local command execution to reduce the network bandwidth and transmission demands; user interaction is achieved by means of a synchronized indicator for pointing out areas of interest and dialog windows for conversation. Because Java programs can run on heterogeneous platforms, the need for system maintenance and user training is minimized. Although the drawback of Internet bandwidth still exists, the system enables platform-independent teleradiology via the Internet and allows easy and cost-effective remote consultation.
