Images provided by different imaging modalities correspond well to the background anatomical knowledge and are therefore well accepted and understood by the medical staff. The contribution of modern imaging to the progress of medicine and level of health care is thus widely recognised. While there is admirable progress in designing new or innovated imaging modalities often based on new physical principles the overall success is equally due to the computational part of the imaging. All modern medical imaging modalities use image data in the digital form. Image reconstruction from incomprehensible projection data their processing noise and distortion removal or various display methods matched to particular needs of diagnostics all depend heavily on the computational aspects of medical imaging. The progress in medical imaging is thus in a great part a success of information processing both on the side of algorithm design and implementation as well as utilising large-scale-integration-based hardware. Without being too visible computers are a substantial part of any modern imaging system and the specialised software forms a great deal of the system value the corresponding algorithms being often the well guarded family silver
