Methods and apparatus for coronary-specific imaging reconstruction

摘要

One embodiment of the present invention provides a method for imaging a selected coronary artery utilizing a computed tomography (CT) imaging system. The method includes utilizing a data compilation of low motion cardiac phases and corresponding coronary artery branch segments to select a cardiac phase corresponding to the selected coronary artery branch segment. A volume of the patient's heart including the selected coronary artery branch segment is scanned to acquire projection data. The projection data includes data acquired during the selected cardiac phase of a plurality of cardiac cycles. Projection data acquired during the selected cardiac phase is selectively utilized to effectively reduce motion artifacts of the selected coronary artery branch segment on a reconstructed image.
