A Multi-Anatomy System for Computing and Centering Field of View from Localizer Images

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.
