Abstract:
1. A method for taking tomograms of a patient's beating heart with the aid of a computed tomography unit, the method comprising: moving at least one focus, with an oppositely situated detector, around the patient to scan the beating heart; recording detector data, output by the detector and representing an attenuation of the beams emanating from the at least one focus, together with indirect or direct spatial orientation data of the beams; recording ECG signals of the beating heart, the detector data and ECG signals being stored in a temporally correlated fashion; and using, to reconstruct the tomograms, detector data that originates from a selected cycle area of a cardiac cycle of the heart, the cycle area being selected automatically and individually per cycle for at least one cardiac cycle by pattern recognition, wherein the using includes before the automatic selection of the cycle area is carried out, a typical signal profile of the current ECG in at least one of the area and an adjacent one is determined manually, and the typical profile is subsequently automatically detected again in at least one cardiac cycle to which the determination of the desired area is oriented for the reconstruction.
