Abstract

The invention relates to a device and a method for determining the optimum image reconstruction phase for objects moving quasi periodically, particularly with regard to the computer tomography (CT) of the heart. One task of the present invention is to enable an automated determining of the optimum image reconstruction phase with regard to the reduction of movement factors. This task is solved by a method for illustration of an object moving quasi periodically using an image recording system (1), particularly a computer tomograph, using a phase-correlated reconstruction technique, in which an optimum image reconstruction phase is determined using a movement function (8) of the object.
