A
system is demonstrated for automatically deriving and centering oblique scan
extents/fields of view (FOV) from localizer scans. Our method differs from prior work in the
field by being marker-less and allowing for automated acquisitions oblique to
the input localizer. By constraining
acquisition to the precise extents of the anatomy being sought acquisition
time is reduced. This acquisition
time reduction is particularly valuable in cardiac and abdominal imaging:
given the need for breath-held scanning.
Furthermore, by prescribing an optimal field of view we can also
reduce potential wrapping artifacts and improve the consistency of image
representation.
