Abstract
A system for correcting for scatter in a computed tomography scanner includes a tunnel having a platform disposed therein for receiving an object to be scanned, an x-ray source for directing x-rays at the object to be scanned, a detector array including a plurality of primary detectors for receiving the x-rays and at least one secondary detector for receiving portion of the x-ray beam scattered within the tunnel. The system further includes processing means for reducing the effects of scatter in images of the object reconstructed from the x-rays detected by method of estimating an amount of scatter caused only by the presence of the object corrected by an amount of scattered x-ray when presence or absence of object.
