It has been shown that joint image reconstruction and sensitivity estimation in SENSE (JSENSE) can improve image reconstruction quality when acceleration factor is high. However, existing methods for JSENSE need long reconstruction time and/or optimal termination condition, which have hindered its clinical applicability. In this work, a fast non-iterative JSENSE technique, based on pseudo full k-space, is proposed to improve the clinical applicability of JSENSE. Using the proposed method, the computation time for sensitivity maps could be reduced from minutes to a few seconds without degrading the image quality.
