Bladder filling and gut peristalsis are significant
confounds to high quality abdominal imaging. As a
result, imaging in this region needs to be performed
rapidly in order to reduce motion-induced resolution
loss. Scans that are sufficiently long in duration to
allow these motions to corrupt the images cannot have
the desired resolution and may provide no more
information than shorter scans. Integration of MR data
into the radiotherapy planning and treatment will have
to be performed within a short time period. The reported
approach allows fast, high-resolution imaging which will
result in more accurate examinations of the lower
abdomen.
