Abstract: A method is disclosed for automatically selecting a scanning protocol for a tomographic recording of an X-ray image of a patient in that at least one patient-specific value is retrieved in the internal memory of a first computer. The patient-specific value can in particular be a measure of the anticipated X-ray absorption by the patient. The method includes automatically comparing the patient-specific value with retrievably stored reference values, wherein one scanning protocol can be associated with each reference value. Finally, a scanning protocol is automatically selected by way of the first computer using the comparison. Selection is simplified by automation of selection of the scanning protocol since no manual selection of the scanning protocol has to be made. Automatic selection of a suitable scanning protocol is also quicker than a manual selection.

Abstract: 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.

The patient-specific examination parameters are electronically stored, and are electronically retrieved to implement a duplicate of the aforementioned procedure in an imaging modality-assisted follow-up examination.

Abstract: Provided is a method for generating views of tomographic image data. At least one view of an object area is generated by image filtering from tomographic CT image data by using a modulation transfer function and coordinate information. A filter algorithm is used for the image filtering and, if appropriate, further view parameters required for generating the view may be stored in a view file assigned to the CT image data. The view file is called up, and the filter algorithm as well as, if appropriate, the further view parameters are applied to the CT image for the purpose of renewed generation of the view.

Abstract: 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.

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.

Abstract: In a tomography-capable imaging examination apparatus, and an operating method therefor, an operator first determines a desired scan volume of the examination subject, and then, controlled by the computer device, a raw data set, having data allocated to different directions, is acquired in the scan volume. For planning the subsequent calculation of the resulting image—keeping pace with the scan or immediately after its termination—the computer device calculates and displays a graphic overview representation of the subject of examination from the raw data. The overview representation contains three-dimensional information about the scan volume. In this volume, the operator selects a diagnostically relevant region of representation. Using an image calculation algorithm, the computer device calculates a diagnostically relevant resulting image in the selected region of representation. The quantity of data thus is reduced immediately upon its origination.
