The development of computer tomography (CT) in radiography has stimulated recent interest in picture archiving and communication systems (PACS) in medicine. Electron microscopy and histopathol-ogy also use interpretation of images in diagnosis. We have implemented a prototype system for on-line digitization of tissue images as a part of PACS based on DEC PDP 8, VAX 11/730 and PDP 11/35 processors. The front end processor was directly connected to a JEOL 100B scanning transmission electron microscope (STEM). Because image digitization results in a loss of information that is present in photography, various methods of image enhancement and filtering were necessary and helpful. Data compression by discrete cosine transform (DCT) retained satisfac-tory image quality at 0.5 - 1.0 bits/pixel. It is also stressed that future PACS in medi-cine must incorporate images of diagnostic histo-pathology and electron microscopy.
