Abstract
A method for obtaining an intraoral x-ray image determines an initial spatial position and angular orientation of an x-ray source relative to a detector. A first x-ray image is obtained with the x-ray source at the initial spatial position and angular orientation and stored, associating the initial spatial position and angular orientation to the first x-ray image. A sequence repeats that calculates a next spatial position and angular orientation for the x-ray source, provides positional adjustment information between the x-ray source and detector for obtaining a next x-ray image, measures and records the actual spatial position and angular orientation of the x-ray source relative to the detector and obtains and stores the next x-ray image at the measured spatial position and angular orientation, and forms a composite image using image data from the first and from the one or more next x-ray images.
