AB Different approaches that use Cartesian trajectories with spiral profiles and golden angle step have been proposed to accelerate MRI acquisition. G-CASPR is characterized by a scheme with uniform k-space sampling and it is usually applied to static MRI. Nevertheless, compressed sensing shows better results if the center of k-space is sampled more densely. VDRad is a variable density sampling scheme that has been reported for abdominal imaging. VDRad, however, has the drawback that some positions in the k-space are repeatedly acquired, decreasing efficiency. We define a versatile sampling scheme that varies continuously from the G-CASPR to VDRad. Our goal is to determine whether intermediate configurations can provide better sampling schemes for cine cardiac MRI applications.
