我们提出了一个广义的delta-Eddington相位函数，将辐射传输方程简化为关于光子通量矢量的积分方程。积分方程的解非常准确，可以在广泛的光学参数范围内对生物组织中的光子传播进行建模，特别是在扩散近似被打破的可见光谱中。该方法在蒙特卡罗模拟中得到了验证，并可应用于各种光学成像应用。(c)2007年，美国光学学会。
We present a generalized delta-Eddington phase function to simplify the radiative transfer equation to an integral equation with respect to the photon flux vector. The solution of the integral equation is highly accurate to model the photon propagation in the biological tissue over a broad range of optical parameters, especially in the visible light spectrum where the diffusion approximation breaks down. The methodology is validated in the Monte Carlo simulation and can be applied in various optical imaging applications. (c) 2007 Optical Society of America.
