ABSTRACT
Java language has been demonstrated to be an effective tool in supporting medical image viewing in Russia. This evaluation was completed by obtaining a maximum of 20 images, depending on the client's computer workstation from one patient using a commercially available computer tomography (CT) scanner. The images were compared against standard CT images that were viewed at the site of capture. There was no appreciable difference. The client side is a lightweight component that provides an intuitive interface for end users. Each image is loaded in its own thread and the user can begin work after the first image has been loaded. This feature is especially useful on slow connection speed, 9.6 Kbps for example. The server side, which is implemented by the Java Servlet Engine works more effective than common gateway interface (CGI) programs do. Advantages of the Java Technology place this program on the next level of application development. This paper presents a unique application of Java in telemedicine.

Figure 3: Patient's data interface of the Remote Image Viewing program

Mentions: The program operates in the following manner. First the client addresses the Hypertext Markup Language (HTML) file through the browser interface, which exports the applet (class-file). This activates a Java Virtual Machine, which starts its implementation (Fig. 2a). After initiation, the applet requests the list of images on the server (Fig. 2b. In its turn, the servlet responds to the applet request by scanning the images directory and sends file names. The number of images visualized simultaneously in the viewport depends on the image size. In the current version of the application, the viewport is limited to 300 × 350 pixels. All images that exceed these limits are viewed with the help of the scrollbars. The efficiency of the image manipulation is dependant on the client's computer work power. A special attention should be paid to the RAM and video memory capacity (each CT image is about 50 Kb). A computer working with Windows OS and 32 MB of RAM can simultaneously handle up to 20 images. A modified Remote Image Viewing application has been specially adapted in order to run a structure of data obtained during investigations of patients on the Bruker CT. The applet has been enhanced to allow viewing of patient's images (Fig 3). The server is able to process patient information data and graphics stored on the server in raw format received directly from the Bruker CT. Information is converted for representation in the browser. To optimize image download, data processing occurs at the first request. Later, the application handles the transformed data array. This sequence significantly accelerates data transfer through the network.
