Method for operating an x-ray computer tomograph

摘要

A selectable mode of operation is disclosed for an X-ray computer tomograph for producing angiographical images. A patient accommodated on a couch is not moved relative to the measuring system in the z-direction, the entire area to be examined is irradiated at a prescribed first angle of rotation of the measuring system, and the X-ray radiation emerging from the area to be examined is detected isochronously using a matrix detector.
