A process for the picture being made in the computer tomography of a periodically moving object to be examined and ct - an apparatus for carrying out the method

摘要

A method for the production of ct - images of a periodically moving examination zone with at least the following method steps:1.1. for the scanning of a periodically moving object to be examined with one of at least a focus outgoing beam, and with a flat detector field with a plurality of distributed detector elements for detecting the rays of the radiation beam, the at least one focus relative to the object to be examined on at least one of the object to be examined, circumferential focus web is moved with opposite detector, wherein the detector elements of the detector field output data, and the weakening of the rays, upon passing through the object to be examined represent,1.2. be it at the same time as the scanning movement data of the periodically moving examination zone is collected, in order to the detector data and the resulting data to be able to allocate the movement condition,the output data are filtered 1.3,1.4. the filtered output data are for the generation of at least one cutting pattern of a layer having a layer thickness of the examination subject three-dimensionally back-projected, whereineach sectional image 1.5. absorption values obtained from the output data..
