Method for reconstruction of a 3D image set of a rhythmically moving object, especially relating to computer tomography of the heart, whereby image recording is carefully correlated with the beating of the heart

摘要

Method for reconstruction of a 3D image data set of an examination area (13) examined using a radiation source (S) and a detector unit (16). The time interval between image recordings is shorter than that of the regular movement cycle of the object. Rotation of the source about a rotation axis (14) is controlled so that over n time intervals it covers an angle greater then 180 deg plus the cone angle ( beta ). Translation of the radiation source is such that its cone beam passes completely through the examination area at every point of the n time intervals. An Independent claim is made for a device for reconstruction of a 3D image data set of an examination area.
