Abstract With the development of molecular imaging, Cherenkov optical imaging technology has been widely concerned.
Most studies regard the partial boundary flux as a stochastic variable and reconstruct images based on the steadystate diffusion equation. In this paper, time-variable will be considered and the Cherenkov radiation emission
process will be regarded as a stochastic process. Based on the original steady-state diffusion equation, we first
propose a stochastic partial differential equation model. The numerical solution to the stochastic partial differential
model is carried out by using the finite element method. When the time resolution is high enough, the numerical
solution of the… More >
