摘要
In multi-slice imaging of a magnetic resonance imaging apparatus based on a non-Cartesian sampling method in which an overlap portion is generated in k space, stable body movement correction is realized at high speed. In order to do so, the rotation and translation of an object is detected for each specific region (in the case of a hybrid radial method, each blade) using a most characteristic slice in the imaging region, and the detected body movement is used for body movement correction of the specific region in all slices. The slice used for correction may be determined using a mathematical analysis result, such as correlation. In addition, data collection and correction processing may be performed in parallel.
