Method for detecting three-dimensional cardiac data of e.g. human being, involves reconstructing obtained data at remaining cardiac phases after completion of forward cycle by completed acquisition of data

摘要

The method involves detecting heart action by electrocardiogram (ECG), and determining heart rate of an examination object i.e. patient. Start-cardiac phase is calculated, and parameters of C-arm planes are calculated from the determined heart rate. Acquisition of data is started at quarter cardiac phase earlier than the start-cardiac phase. The C-arm planes are uniformly rotated with same speed in same rotation direction as another forward cycle. The obtained data are reconstructed at remaining cardiac phases after completion of the latter forward cycle by completed acquisition.
