AI Technical Summary

Technical Problem

Existing X-ray systems lack accurate monitoring of X-ray source output energy distribution, particularly in systems using a fan-shaped beam, which affects the quality and consistency of imaging results.

Method used

A segmented detector is positioned to cover at least two angular ranges of the fan-shaped beam, generating two sets of energy distribution data to determine the initial and final electron energy, enabling precise monitoring of X-ray source output.

Benefits of technology

Enhances the accuracy and consistency of X-ray source energy monitoring, improving imaging quality by providing precise energy distribution data.

Abstract

Systems and methods to monitor output energy of an X-ray source being used to emit a fan beam for scanning an object in a scanning system include a segmented detector positioned between a target of the X-ray source and the object. The segmented detector has at least two segments that are placed to cover at least two angular ranges of the fan beam and generate corresponding two sets of energy distribution data. A ratio is determined based on the two sets of energy distribution data in order to determine an initial electron energy and an end-point energy of the X-ray source based on the ratio.
