Abstract

Random walk theory is used to calculate a time-dependent contrast function to interpret data obtained from time-resolved transillumination detection of abnormally absorbing regions in tissue. The contrast function depends on the optical properties of the normal tissue as well as the absorptivity, size and location of the abnormal target. Results of the theory are applied to estimate the absorption coefficient of a cylinder target embedded in a tissue-like phantom. Extrapolation of the time-dependent contrast function to short times enables one to enhance the contrast and resolvability of the abnormal region.
组织中异常吸收区的光学检测
随机游走理论用于计算时间相关的对比函数,以解释从组织中异常吸收区域的时间分辨透照检测获得的数据。对比功能取决于正常组织的光学特性以及异常目标的吸收率、大小和位置。将理论结果应用于估计嵌入在类组织模体中的圆柱体目标的吸收系数。将时间相关的对比函数外推到短时间,可以增强异常区域的对比和可分辨性。
