Abstract
The present invention, in one form, is a pre-patient collimator for reducing patient x-ray dose during a scan with a computed tomography system. The collimator has a contoured aperture for emitting a generally rectangular shaped x-ray fan beam. The fan beam approximates the rectangular shape of x-ray detectors which gather data for producing an image.
