Method and apparatus of CT cardiac diagnostic imaging using motion a priori information from 3D ultrasound and ECG gating

摘要

ECG and ultrasound data of the heart are acquired in real-time during a scan. A data acquisition module is controlled during the scan to prospectively gate acquisition of CT data as a function of the real-time ECG data and the real-time ultrasound data. An image is reconstructed from the acquired CT data.
