Abstract
A system for parallel image processing in MR imaging uses multiple MR imaging RF coils to individually receive MR imaging data representing a slice of patient anatomy. An MR imaging system uses the multiple RF coils to acquire corresponding multiple image data sets of the slice. A coil selection processor determines a prioritized ranking of the multiple RF coils by ranking individual coils of the multiple RF coils based on correlation with remaining coils of the multiple RF coils. The correlation being determined by determining degree of correlation of image data sets acquired by respective coils of the multiple RF coils. The coil selection processor selects a subset of the multiple RF coils using the ranking. An image generator generates a composite MR image using image data sets provided by the selected subset of the multiple RF coils excluding image data sets provide by remaining coils of the multiple RF coils.
