We benchmark the current existing methods to jointly learn non-Cartesian
k-space trajectory and reconstruction: PILOT, BJORK, and compare them with
those obtained from the recently developed generalized hybrid learning
(HybLearn) framework. We present the advantages of using projected gradient
descent to enforce MR scanner hardware constraints as compared to using added
penalties in the cost function. Further, we use the novel HybLearn scheme to
jointly learn and compare our results through a retrospective study on fastMRI
validation dataset.
