摘要： A system is disclosed for generating, evaluating and distributing computer-tomographical 4D representations of the heart of a patient. The system includes a cardio CT appliance, where a first low-resolution reconstruction of cardio recordings in a multiplicity of cycle phases of the cardiac cycle and subsequent volume rendering of these cardio recordings for 3D representation and examination of the clarity of motion of the representation in the individual cycle phases are performed. This representation is used to select one or two cycle phases with a relatively reduced or even minimal lack of clarity of motion. High-resolution representations of the heart are reconstructed for these selected one or two cycle phases, with the computation and control unit transmitting only the high-resolution representations of the selected cycle phases with a relatively reduced lack of clarity of motion to the at least one workstation as still images, and the workstation being used to perform the evaluation.

摘要： A method and a system are disclosed for computed tomography illustration of the movement of a heart in the cardiac cycle with the aid of a spiral CT. In the method, a patient is administered a contrast medium via an electronically controllable apparatus. A stationary prescan of a cardiac artery is carried out in order to determine the sufficient filling of the artery with the automatically applied contrast medium. When a sufficient contrast medium filling is detected, the current heart rate of the heart being examined is measured, and a maximum possible feed rate for a spiral scan and a duration of the spiral scan are determined on the basis of the current heart rate. Subsequently, the spiral scan is carried out over the heart region with the maximum possible feed rate.
