1. A method, comprising:
receiving a preoperative image depicting the spine of a patient in a first posture;
receiving an intraoperative image depicting the spine of the patient in a second posture while the patient rests on a surgical table in an operating room;
comparing the preoperative image of the patient in the first posture with the intraoperative image of the patient in the second posture;
determining, based on comparing the preoperative image of the patient in the first posture with the intraoperative image of the patient in the second posture, a difference between the first posture and the second posture;
determining, based on the difference between the first posture and the second posture, an alignment of a first segment of the spine of the patient with a second segment of the spine of the patient;
providing, via a display in the operating room, a suggested intraoperative motion during a surgery or surgical procedure to move the patient on the surgical table from the second posture to a third posture to reduce the difference between the second posture and the first posture, wherein the suggested intraoperative motion is provided before a spine of the patient is surgically manipulated; and
updating, when the alignment of the first segment with the second segment falls below a threshold value after the patient is moved to the third posture, a planned spinal fusion of the first segment.
