| '''Photon diffusion equation''' is a second order [[partial differential equation]] describing the time behavior of photon fluence rate distribution in a low-absorption high-scattering medium.

| Its mathematical form is as follows.
| |
| <math>\nabla(D(r)\cdot\nabla)\Phi(\vec{r},t)-v\mu_a(\vec{r})\Phi(\vec{r},t)+vS(\vec{r},t)=\frac{\partial\Phi(\vec{r},t)}{\partial t}</math>
| |
| where <math>\Phi</math> is photon [[fluence rate]] (W/cm<sup>2</sup>), <math>\mu_a</math> is absorption coefficient (cm<sup>−1</sup>), <math>D</math> is [[diffusion constant]], <math>v</math> is the speed of light in the medium (m/s), and <math>S</math> is an isotropic source term (W/cm<sup>3</sup>).

| | |
| Its main difference with [[diffusion equation]] in physics is that photon diffusion equation has an absorption term in it.
