We developed a new technique, named Highly Accelerated Projection Imaging (HAPI) with coil sensitivity encoding, which is capable of reconstructing a 2D image using fewer projections than the previous reports. The essence of this new technique is to sample each spoke more densely than the conventional scheme. The feasibility of this new technique was investigated with realistic simulations and experimental phantom studies. Simulation results show that 1-2 projections might be sufficient to reconstruct a 2D image. Experimental results demonstrated that HAPI is a promising new technique for fast imaging.
