1. A method comprising:
performing a first manual rotation of an imaging arm of an x-ray imaging apparatus;
obtaining, using a detector carried by the imaging arm, a plurality of first images of a set of fiducial markers during the first manual rotation;
obtaining, using a motion sensor coupled to the imaging arm, first pose data of the imaging arm during the first manual rotation;
determining, using one or more processors, a set of calibration parameters for the x-ray imaging apparatus based on the first images and the first pose data;
performing a second manual rotation of the imaging arm of the x-ray imaging apparatus;
obtaining, using the detector, a plurality of second images of an anatomic region of a patient during the second manual rotation;
obtaining, using the motion sensor, second pose data of the imaging arm during the second manual rotation; and
generating, using the one or more processors, a 3D representation of the anatomic region based on the second images, the second pose data, and the calibration parameters.
