Abstract:
1. An imaging method comprising: receiving an image data record of a recording region of a patient, the region being influenced by a cyclical cardiac motion which cycles at a cycle duration; registering an EKG signal of the cardiac motion of the patient; determining a dispersion parameter, the dispersion parameter indicating a variation in the cycle duration, determining a weight given to the dispersion parameter based on an expected value of the cycle duration, deriving a series of recording pulses from the EKG signal, matched to the cardiac motion by calculating a time window of a future recording pulse such that a size of the time window is based on at least (i) the dispersion parameter, (ii) the determined weight given thereto, and (iii) a cardiac frequency of the cyclical cardiac motion, and actuating a CT scanner in a pulsed fashion according to the requirements of the derived recording pulses to generate an image.
