ABSTRACT:
A method and a CT system are disclosed for carrying out a cardio-CT examination of a patient. The patient first is scanned using a first X-ray spectrum by way of at least two X-ray tubes at a first relative position, until the measurement data has been gathered from a determined heart phase for parallel projections over a range of in total at least 180° of projection angles. The patient is then scanned, without changing the position of the gantry, at the first relative position by way of at least two X-ray tubes using at least one second X-ray spectrum, until the measurement data has been gathered from a determined heart phase for parallel projections over a range of at least 180° of projection angles, upon which the next relative position between the patient and the gantry is moved to.
