We set up a server and client system with CTN server (Mallinkrodt Institute of Radiology) and personal computer (PC) client to evaluate medical image database from practical point of view. We prepared 189 CT images of a single study. The images had been stored in ACR-NEMA Ver.2 format. We transformed the image data to DICOM3 format using a batch program. The maximum number of images in a series was limited to a hundred in CTN software. On the PC client, the images were displayed in an unexpected order. The reason of the problem was that the DIC-OM3 has not a query and retrieve service for an acquisition number. It is necessary to set up a supplemental data-base system to retrieve proper images from the image server.
