Velocity Encoded Phase Contrast (VE-PC) imaging is an established technique for monitoring muscle kinematics. Dynamic studies require consistent repeated execution of motion paradigms to map skeletal motion. The high number of repeated contractions limits studies to low % maximum voluntary contraction and limits participation of cohorts with compromised muscle function. We explore combining multi-coil data with compressed sensing and reconstruction to reduce acquisition times. VE-PC images acquired with different compressed sensing factors are assessed for accuracy of velocities and strain rate tensor during isometric contractions. Our results show that CS undersampling by 4 yields accurate velocity and strain tensor values.
