摘要：
An MR system compensates for patient movement by generating a magnetic field for acquiring, first data representing individual frequency components of a segment of a k-space storage array during a first time period and second data representing individual frequency components of the segment of the k-space storage array during a subsequent second time period. The first and second data comprise individual frequency components of different images of a portion of the anatomy of a patient. The system uses the first and second data in calculating a measure representing degree of patient related motion occurring between acquisition of the first data and second data and generates an image by excluding frequency components of the first data and second data in response to the calculated measure exceeding the predetermined threshold value.
