在X线直接数字成像系统上进行双能量分离成像

Dual-energy Separation Imaging on An X-ray Direct Digital Imaging System

研究了一种基于X线直接数字成像系统的胸部骨和软组织双能量分离的方法。文中讨论了高能X线束滤过板的最佳厚度。在进行双能分离运算之前，我们对原始X线图像进行了散射校正。研究结果表明利用广谱X线束获取双能量X线图像并将其用于常规检查是可行的。

A method of dual-energy separation of bone and soft tissue images of chest based on an X-ray directdigital imaging system has been investigated. In this paper, the optimal thickness of the filter for high energy Xray beam is discussed. An algorithm of correction of scattered radiation is employed before the separation algorithm. The separated images will be shown in the paper. The result shows that it is possible to use an ordinarybroad spectral X-ray beam to acquire the dual-energy images for routine X-ray diagnosis.
