我们提出了一个框架，光学层析成像的基础上的路径积分。而不是直接求解的辐射传输方程，这已被广泛用于光学层析成像，我们使用的路径积分，已开发用于渲染参与媒体的基础上，在计算机图形学的体绘制方程。对于离散化的二维分层网格，我们开发了一种算法来估计每个体素的消光系数与内点法。数值仿真结果表明，所提出的方法是有效的。
We present a framework for optical tomography based on a path integral. Instead of directly solving the radiative transport equations, which have been widely used in optical tomography, we use a path integral that has been developed for rendering participating media based on the volume rendering equation in computer graphics. For a discretized two-dimensional layered grid, we develop an algorithm to estimate the extinction coefficients of each voxel with an interior point method. Numerical simulation results are shown to demonstrate that the proposed method works well.
