  • Patent number: 6215853
    Abstract: The present invention provides a method and apparatus for calibrating the size and alignment of a collimator. The method includes the step of acquiring a digital image showing collimator blades in front of a region of interest. The method then determines the position of one or more of the collimator blades or collimator assembly shown in the digital image. The method subsequently adjusts the position of one or more collimator blades toward a predetermined position with respect to the region of interest. Calibration may iterate until the collimator exposes a region of interest to within a predetermined tolerance.
