1. A processor-implemented method to intraoperatively determine a suitability of an intraoperative image for further intraoperative surgical analysis, the method comprising:
determining, based on at least three pelvic feature points in a pre-operative image, a first angle;
determining, based on at least three corresponding pelvic feature points in a first intraoperative image, a corresponding second angle;
determining the suitability of the intraoperative image for the further intraoperative surgical analysis based on a comparison of the first angle and the corresponding second angle; and
in response to a determination that the first intraoperative image is not suitable for the intraoperative surgical analysis, providing an indication of a movement direction for a fluoroscopy camera used to obtain the first intraoperative image.
