Abstract: A method of maintaining patient registration in surgical navigation includes: obtaining a patient position in a tracking system frame of reference, based on a fiducial marker array affixed in a first position relative to the patient; receiving an initial surface scan depicting the patient and the fiducial array; responsive to receiving an intraoperative image depicting the patient: obtaining a position, in the tracking system frame of reference, of the fiducial array affixed in a second position relative to the patient; receiving a secondary surface scan depicting the patient and the fiducial array; detecting a deviation in a position of the fiducial marker array relative to the patient between the initial and secondary surface scans; and applying the deviation to the position of the patient to generate an updated position of the patient in the tracking system frame of reference, based on the fiducial array affixed in the second position.

Abstract: A medical imaging system for determining a scan orientation is provided. The system comprises: a computing device; a display device; an input device; and, an imaging device, the computing device configured to: instruct the imaging device to acquire at least a sagittal scout scan, an axial scout scan and a coronal scout scan, based on an initial frame of reference; render, at the display device: a two-dimensional representation of each of the scout scans and initial respective selections of a portion of each of the scout scans, oriented according to the initial frame of reference; receive, from the input device, a respective reorientation of one or more of the initial respective selections; transform the initial frame of reference using the respective to produce a reoriented frame of reference; and, instruct the imaging device to acquire further images based on the reoriented frame of reference.
