Turbo spin echo (TSE) sequence is one of the “workhorses” used in routine clinical applications for MR imaging [1]. However, long scan time and segmented k-space acquisition make it particularly susceptible to artifacts due to motion, not only between echo trains but also during echo train. When correcting such motions prospectively, a signal loss might be induced due to noise in motion tracking data. In this work, we present an analysis linking tracking noise to the signal drop. A sequence optimization approach predicts that intra-echo train motion correction with the available optical tracking system should be feasible without signal loss.
