ABSTRACT
A modern trend is to provide computer-aided diagnosis support to medical experts. Medical imaging became a very interesting field concerning both the physical principles of the imaging modalities and the aspects of image data processing. The tendency to automate mechanical operations, namely, by applying knowledge-based approaches, is continuing; it can hardly be expected that the human factor of medical expert supervision would be eliminated from the process of image processing and evaluation in a foreseeable future. When specifying the hardware to be used for medical image processing and evaluation, general ergonomics should be considered as well with respect to the possibility that a concrete type of work will be performed by a radiologist or another medical expert for a long time. Most modern image formats keep the image data in a compressed form, i.e., image data are transformed so that they have a smaller extent but preserve all or a substantial part of the medically important image content.
