A series of Monte Carlo simulations have been performed in order to investigate the feasibility of constructing a time-of-flight transillumination imaging system that could be used as an effective tool for screening for breast disease. The conceptual design of such a system is described, and simulated images are presented that demonstrate its likely performance. It is found that, whereas the spatial resolution achievable with such a system is only dependent upon its temporal resolution, the scattering characteristics of the tissue being imaged will strongly affect the ultimate imaging performance of such a system.
为了研究构建一个飞行时间透照成像系统作为筛查乳腺疾病有效工具的可行性,已经进行了一系列蒙特卡罗模拟。描述了这种系统的概念设计,并给出了模拟图像以展示其可能的性能。研究发现,虽然这种系统可实现的空间分辨率仅取决于其时间分辨率,但被成像组织的散射特性将强烈影响该系统的最终成像性能。
