title: [Computed tomography--basic principles and outlook for related procedures].
abstract: The computerized X-ray tomography uses for the information of the images besides a highly developed computer technology a special CT-algorithm, i.e. preprocessing of detected "projections", their "high-pass" convolution and back-projection. The diagnostic success of computerized X-ray tomography gave rise to the investigation of other carriers of information besides X-radiation for the production of cross-sectional pictures using CT reconstruction principles. Examples are: Emission-CT, Proton-CT, Nuclear Magnetic Resonance CT, Ultrasound-CT, Impedance-CT and Mikrowave-CT. This paper gives a review of such methods, their basis properties and an estimation of their capabilities for medical application. This discussion is opened by a summary of the basis CT principles.
