已经设计了一种使用宽缝光束和简单的反散射栅格或狭缝的系统，以提供组织类型的局部地图，该局部组织类型地图可以覆盖在同时的常规传输图像上，以提供传统筛查乳房X光检查的廉价、低剂量的附件。可以从立体视角获得深度信息。该系统被证明在脂肪组织和被选来模拟癌症的体模之间产生明显的对比度，曝光时间与筛查乳房X光照相相当。成像数据是在一系列系统参数上收集的，以优化对比度并允许验证模拟建模。(C)2016年光学仪器工程师学会(SPIE)
A system using a wide-slot beam and simple antiscatter grids or slots has been designed to provide a localized map of tissue type that could be overlaid on the simultaneous conventional transmission image to provide an inexpensive, low dose adjunct to conventional screening mammography. Depth information is obtainable from the stereoscopic viewing angles. The system was demonstrated to produce observable contrast between adipose tissue and a phantom chosen to mimic carcinoma at an exposure comparable with screening mammography. Imaging data was collected over a range of system parameters to optimize contrast and to allow verification of simulation modeling. (C) 2016 Society of Photo-Optical Instrumentation Engineers (SPIE)
