Cone-beam X-ray luminescence computed tomography (CB-XLCT) contributes to medical imaging, with its non-invasive animal imaging applications. When imaging a biological tissue, it is essential to obtain its optical properties. Monte Carlo simulation offers a flexible and rigorous approach to photon transport in turbid tissues. With Monte Carlo simulation, multiple physical quantities can be obtained. In our CB-XLCT system, Monte Carlo-based forward and inverse model were used to help the image construction of the system by extracting the absorption and scattering coefficients of turbid media
