正在开发一种成像系统，作为使用无害剂量的可见光或近红外辐射筛查乳腺癌的可能手段。该系统通过记录和区分透射光子的飞行时间来产生高度散射物体的透射图像。已经进行了实验来评估这样的系统的可能的空间分辨率性能。这涉及到测量嵌入在高散射介质中的不透明掩模产生的边缘轮廓，并评估作为透射光积分时间段的函数的空间分辨率。结果表明，几毫米的分辨率是可以实现的系统与时间分辨率约为10 ps。
An imaging system is being developed as a possible means of screening for breast cancer using harmless doses of visible or near‐infrared radiation. This system produces transmission images of highly scattering objects by recording and discriminating between the times‐of‐flight of transmitted photons. Experiments have been performed to evaluate the likely spatial resolution performance of such a system. This involved measuring the edge profile produced by an opaque mask embedded in a highly scattering medium, and evaluating the spatial resolution as a function of the period of time over which transmitted light was integrated. The results suggest that a resolution of a few millimeters is achievable with a system with a temporal resolution of about 10 ps.
