Abstract
A monitoring detector assembly is positioned outside the scanning plane of a CT scanner to insure detection of unattenuated X-rays from the X-ray source of the scanner. The monitoring detector assembly preferably provides a sequence of monitor detection measurements simultaneously with the sequential acquisition of the image data during each projection of the scan by a filtered CT scanner. The image data are normalized using the closest in time monitor detection measurement.
