Provided is a method for preventing image quality degradation that occurs when a predicted value of an RR interval deviates from an actual interval because the RR interval fluctuates mainly due to respiration in electrocardiographic synchronization imaging. To do. The time from the R wave to the diastole is derived using the position of the diaphragm detected in the navigation sequence, and measurement is performed after the systole derived when the position of the diaphragm is within a predetermined range. . Alternatively, the T wave of the electrocardiogram is detected, the heart diastole is derived from the detection timing of the T wave, and imaging is performed in the diastole when the diaphragm is at a predetermined position. As a result, it is possible to prevent image deterioration in delayed contrast and ECG synchronization. [Selection] Figure 6 |
