| Abstract(in English) | The purpose of this study is to improve an automated method without user interaction for selecting optimal data acquisition window in coronary MRA. One of the major problems of magnetic resonance coronary angiography (MRCA) is the effective suppression of coronary motion due to respiration and cardiac contraction. To compensate for cardiac movement, data acquisition is generally limited to the coronary artery rest period mainly found during end-diastole. End-diastole is called cardiac rest period. Generally, cardiac rest period is decided by operator. Therefore it is subjective, and requires much experiences. We already proposed a method that is based on the extraction of intensive change regions and the calculation of the correlation coefficient. As for setting region of interest including right coronary, there are still several errors. To improve the accuracy, we propose a new method to determine cardiac rest period based on the tracking of right coronary directly and show the results. |
