This paper reviews a few of the more recent and most successful applications of medical imaging that have exploited the spatial resolution of computed tomography (CT) systems. Spatial resolution is, at this time, a distinguishing feature of high resolution CT scanners when compared to other medical imaging modalities. The purpose of this paper is to highlight these promising applications of digital imaging in medicine and similar applications of computer graphics, computer communications and bio-engineering that will develop using magnetic resonance and the new technologies that follow. Stereotactic techniques for neurosurgery and more recently orthopaedic surgery are outlined. In addition, techniques for custom structure modelling and prostheses planning and manufacturing are discussed. Finally, emerging issues of computer communications and their application to clinical imaging are introduced.
