Photon Fluence and Dose Estimation in Computed Tomography using a Discrete Ordinates Boltzmann Solver
Edward T. Norris, Xin Liu
In this study, cone-beam single projection and axial CT scans are modeled with a software package - DOCTORS, which solves the linear Boltzmann equation using the discrete ordinates…
