Abstract: A method of calibrating a system for imaging a subject is provided. The method includes determining a position of an X-ray source of the system operative to transmit X-rays through the subject; and calibrating the position of the X-ray source with respect to a detector of the system, based at least in part on a field of view of the X-ray source, the detector operative to receive the X-rays transmitted by the X-ray source. In embodiments, the method includes positioning an X-ray source of the system via a controller at one or more calibration positions based at least in part on at least one camera of the system. In such embodiments the X-ray source is disposed on a mobile arm and operative to transmit X-rays through the subject, and a field of view of the X-ray source is directed substantially towards the detector at each of the calibration positions.
