Abstract
This specification describes an X-ray scanning system that adaptively generates a scatter signal, in the course of a single scan, based on the detected brightness areas of a scanned object. An X-ray source is configured to emit an X-ray beam towards an area over a target object. At least one detector detects radiation scattered from the target object and generates a corresponding scatter radiation signal. The scatter radiation signal is characterized, at least in part, by one or more brightness levels corresponding to one or more scanned areas of the target object. A feedback controller receives the scatter radiation signal from the detector, generates a signal that is a function of the one or more brightness levels and that is based on the received scatter radiation signal, and transmits the signal to the X-ray source. In response, the X-ray source is configured to receive the signal and adjust the X-ray beam intensity based on the signal.
