Abstract

A linear-array, silicon pixel detector, capable of counting single photons, was applied to mammography by using a synchrotron radiation beam. Images were obtained of both a mammographic phantom and a breast-tissue sample. The phantom image was acquired with a mean glandular dose of 0.32 mGy. This detector combined with a synchrotron radiation beam allows acquisition of high-contrast, low-dose images of soft tissues.

摘要

一种能够对单个光子进行计数的线性阵列硅像素探测器，通过使用同步辐射光束应用于乳腺摄影。获得了乳腺摄影体模和乳腺组织样本的图像。体模图像是在平均腺体剂量为0.32毫戈瑞的情况下采集的。这种探测器与同步辐射光束相结合，能够采集软组织的高对比度、低剂量图像。
