A novel compression method, shot-coil compression, is developed and implemented to a k-space reconstruction method SYMPHONY for computation acceleration. By this technique, high resolution multishot diffusion images can be reconstructed with much less reconstruction time. The basic idea of the proposed method is to remove the redundant multi-coil and multi-shot data while reserving most useful information. Simulation and in-vivo experiment were designed and the results validated the effectiveness of the shot-coil compression method.
