Abstract
The present invention is a directed method and apparatus for collimating a radiation beam such that the full intensity of the radiation beam does not impinge detectors of a radiation detector assembly that are particularly susceptible to saturation or over-ranging. This collimation can be dynamically adjusted on a per view basis using empirical or scout scan data.
