Telepathology systems will be common systems in hospitals. The two systems were designed and implemented in web environments for test. One was implemented with the Common Object Request Broker Architecture (CORBA) technique. The other system was implemented in the form of ActiveX. The histopathological materials were stained by Hematoxylin and Eosin. By the Donpisha CCD camera attached to an Olympus BX-51 optical microscope 180 color images come to be acquired. For evaluation of the systems, transmission times and telediagnosis concordance rates were measured. Image processing ability was tested using two telepathology systems. For the local area test, system I using CORBA had measured image transmission times of 0.1 s, 0.2 s, and 0.4 s at the file sizes of 100 K byte, 900 K byte and 3.6 M byte respectively. Transmission times for system II using Component Object Model (COM) were slightly slower, ranging from 0.02 s to 0.05 s. In the long distance area test, system II transmission times were 0.5 s, 0.8 s, and 2.0 s. The overall concordance rate of telediagnosis for the 180 images was 78.3%. In this study, we compared our systems about image transmission, and processing for the further development of system configurations.
