脉冲辐射成像绝对测量方法研究

Absolute measurement of pulsed radiation imaging

设计了一种高透过率、能量响应平坦的探测器,利用该探测器将脉冲射线源图像与射线强度直接关联,简化了图像诊断系统绝对测量的标定环节,建立了脉冲辐射源图像诊断定量化的新技术方法.实验表明,由该方法得到的射线绝对强度的不确定度为33%.

A high transmittance, flat energy spectrum response detector is designed. The relationship between the image and absolute intensity of the pulse radiation is established via a detector, which simplifies the calibration of the absolute measurement in the imaging system. And a new technical approach to the absolute imaging diagnosis for the pulsed radiation is developed. The experiments show that the uncertainty of the absolute intensity measured by this technology is 33%.
