Patent ID: 7336763

Claim:
An extra-oral dental x-ray imaging system comprising: a. an x-ray source adapted for generating x-rays for exposure of such x-rays to an object to be imaged; b. an x-ray imaging device adapted for producing multiple frames during at least part of the exposure; c. a manipulator for moving the imaging device between two consecutive radiated frames during exposure, the moving being of an amount greater than half the width of a pixel in the direction of movement to provide an overlap between consecutive frames of a significant portion of the frame width, the manipulator controlling movement of the x-ray source and the imaging device about at least one rotational axis around which at least one of the x-ray source and imaging device rotates along a spline, the axis being located between the x-ray source focal point and the x-ray imaging device; and, d. a fast memory having an access and storage speed comparable to a readout speed of the x-ray imaging device, the memory storing and holding substantially all the frames produced, and the stored and held frames being individually selectively accessible.
