Patent ID: 8489175

Claim:
A method for recording a plurality of images of an organ of a live body cyclically having a first movement phase suitable for recording and a second movement phase not suitable for recording, comprising: determining a reference signal representing a current movement phase of the organ; modulating an angular velocity of a recording device based on the reference signal, wherein the recording device comprises an x-ray source/detector system; rotating the recording device at a nominal angular velocity during the first movement phase in a first angle range at a first direction, the nominal angular velocity is selected based on an imaging rate of the recording device; recording the images of the organ from a plurality of different angle positions in the first angle range during the first movement phase; determining a differential angle with an image recording rate at the nominal angular velocity of the recording device selected at a rate as high as possible to allow for a quasi-continuous acquisition of images around an overall angle range comprised of the different angle positions; differing by the differential angle the plurality of different angle positions adjacent to each other; adjusting the differential angle by way of an image recording rate of the recording device; reducing the nominal angular velocity of the recording device during the second movement phase in the first angle range followed directly after the first movement phase in the first angle range; rotating the recording device at a direction opposite the first direction during the second movement phase in the first angle range; and accelerating the recording device at the first direction to reach the nominal angular velocity at an end of the first angle range that is a start point of the first movement phase in a second angle range followed directly after the second movement phase in the first angle range such that images recorded in the second angle range are done so at the nominal angular velocity used during the first movement phase.
