摘要
An MRI includes imaging and receiving coils and a controller in communication with the coils which controls the coils to sample k space associated with a patient in a pattern based on knowledge of k-space data and reconstructs an image of the patient from the sampled k-space. The MRI acquires preliminary k-space data of a patient indicating the extent of k-space data for all receiver channels using the coils. The controller determines signal regions associated with the k-space that multiple acquisition blades will target with the coils based on the preliminary k-space. The MRI samples each region with the blades to obtain k-space data and stores the k-space data. The controller interpolates the k-space data to fit in a regular rectangular grid fits each separate blade of k-space data to the grid and averages overlapping k-space data. The MRI reconstructs an image from the k-space data.
