Image recording method and tomography device for fast scanning of a patient affected by breathing movement of a patient receiving area

摘要

Image recording method for fast scanning of a patient by (1) affected recording area (2) using a tomography device (3) with at least two rotatable about a common axis of rotation (4) arranged receiving systems (5, 6, 7, 8), in which At least one recording pulse (10) adapted to the respiratory motion is generated with a respiratory signal (9), with which the tomography device (3) is controlled so that projections (11, 12) are detected by the recording area (2) during the recording pulse (10) wherein projection gaps (13) of the receiving area (2) in captured projections (11) along a first spiral track (14) around the receiving area (2) with the first recording system (5, 6) by projections (12) along a second spiral path (15 ) are filled to the receiving area (2) with the second recording system (7, 8), wherein the recording pulse (10) based on the breath signal (9) from a number of previous breathing cycles (Zi) stati and two consecutive respiratory signal peaks (P-1, P-2) for determining the position and the length of a cycle duration (A-2) are estimated, and the acquisition pulse (10) relative to this cycle duration (A-2 ).
