Claim 18:
19. A method for geometric calibration of an intraoral tomosynthesis imaging system, the method executed at least in part by a computer and comprising:
coupling an intraoral detector with a calibration phantom that includes a first set of radio-opaque markers distributed along a first plane and a second set of radio-opaque markers distributed along a second plane;
positioning the intraoral detector within the mouth of a patient;
directing x-ray radiation from an x-ray source toward an intraoral detector from a plurality of angles with respect to the detector;
and
acquiring image data from the intraoral detector and calculating the relative location of the x-ray source with respect to the detector at each of the plurality of angles, according to detected marker position;
and
obtaining one or more depth-resolved images using an ultrasound or optical coherence tomography system and reporting patient movement detected during tomosynthesis image data acquisition.
