We build a deep neural network in time-phase encoding plane (t-y) for compressed sensing cardiovascular CINE MRI. Previously neural networks were developed in cross-sectional image planes (x-y). A hierarchical convolutional neural network (CNN), known as U-net is used. By adopting the t-y plane, instead of the x-y plane, simultaneous restoration in time and space is effectively achieved. By computer simulation, the proposed deep neural network based on the t-y plane shows better cross-sectional images, clearer temporal profiles, and less normalized mean square errors compared to that of the x-y plane.
