There is a need for faster acquisitions of the MSK system. Particularly, for assessing the ACL at different degrees of flexion, and even better, for dynamic studies. Our work proposes how to obtain quasi-static images of the MSK, in particular for the study of the Anterior Cruciate Ligament (ACL), using smaller and less rigid coils by undersampling and compressed sensing reconstruction.
