Automatic determination of an optimum heart phase for computer tomography reconstruction, masks a motion map from image data sets to determine movement minima for the systolic and diastolic end phases

摘要

For the automatic determination of an optimum heart phase, for a cardio computer tomography (CT) reconstruction, the heart region is scanned by a spiral CT assembly to give a number of image data sets (13) for the production of a motion map (14). The motion map is masked for paired motion minima (Md,Ms) to be established in each masked zone (14.1) The minima are arranged for the heart systolic or diastolic end phase for the reconstruction of at least one image data set with a second resolution for display.
