Abstract:
1. An apparatus comprising: a cardiac cycle feature predictor that predicts a temporal location of a feature of a cardiac cycle of a patient; a scan controller that uses a measured temporal location of the feature of the cardiac cycle of the patient and the predicted temporal location to cause a computed tomography scanner to acquire first prospectively gated projection data sufficient to reconstruct image-space data indicative of a region of the heart at a predicted quiescent phase of a first cardiac cycle of the patient; and an error identifier that identifies an error between a phase at which the projection data was acquired and the quiescent phase; wherein, depending on the identified error, the scan controller causes the scanner to acquire second prospectively gated projection data at a predicted quiescent phase of a second cardiac cycle of the patient that is subsequent to the first cardiac cycle.
