Fast Spin-Echo (FSE) images are routinely acquired
clinically due to their contrast range and fast
acquisition. In the presence of rigid-body patient
motion, however, the excitations in FSE correspond to
different patient positions, resulting in
motion-corrupted images when using standard
reconstruction. Here we present a reconstruction method
which can inherently estimate the level of rigid-body
motion in FSE data, and produce images without blurring
and artifacts. We demonstrate that the method provides
better image quality than conventional reconstruction in
the presence of rigid-body motion, and is useful for
clinical FSE investigations requiring high quality
images free of motion corruption.
