Abstract

The results of a Monte Carlo computer simulation of photon transport through biological tissue are presented. A comparison is made of the performance, in terms of resolution for a given signal-to-noise ratio, of spatial filtering, time-of-flight imaging and a combination of these approaches. The results show that a careful choice of time gate and aperture dimensions can significantly improve the performance of time-gated optical imaging systems.

空间滤波对飞行时间成像系统性能的影响
本文给出了光子在生物组织中传输的蒙特卡罗计算机模拟结果。在给定信噪比的分辨率方面,对空间滤波、飞行时间成像和这些方法的组合进行了性能比较。结果表明,精心选择时门和孔径尺寸可以显著提高时门光学成像系统的性能。
