Figure 1From: Highly efficient respiratory gating in coronary MR employing non-rigid retrospective motion correctionThe effect of motion during a multi-shot scan can be written as matrix equation. TI are motion operators which describe the motion per voxel from the reference to the respiratory state at the given shot. EI and EH are standard sampling operators and their Hermitian conjugate, respectively. The '+' indicates the pseudo-inverse.Back to article page
