Abstract
Official abstract text for this publication.
A method for recording a four-dimensional angiography data record using an x-ray facility with a C-arm is proposed. Projection images are recorded from different projection directions at different time points of the cardiac cycle. A number of three-dimensional reconstruction image data records assigned respectively to a time segment of the cardiac cycle are reconstructed from the projection images and combined to form the four-dimensional angiography data record by temporal assignment in respect of the cardiac cycle. At least one recording parameter describing the temporal sequence is selected when recording the projection images as a function of cardiac stimulation performed to ensure a stable heart rate during recording so that the recording of the projection images takes place in such a manner that it is synchronized with the cardiac cycle.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for recording a four-dimensional angiography data record using an x-ray facility with a C-arm, comprising: recording projection images from different projection directions at different time segments of a cardiac cycle of a patient; reconstructing a number of three-dimensional reconstruction image data records assigned respectively with a temporal assignment to a time segment of the cardiac cycle from the projection images; and combining th…
