We propose an adaptive coil selection scheme for self-gated coronary MRI. The coil selection is based on the motion profile observed by numerous receive coils. Coils which do not receive the respiratory motion trend are discarded. This allows for an adaptive number of discarded coils based on the size of the region of interest. Coil selection can be used to reduce the amount of data, accelerating data handling and post-processing.
