Acuros<scp>CTS</scp>: A fast, linear Boltzmann transport equation solver for computed tomography scatter – Part I: Core algorithms and validation

Abstract

Acuros CTS enables a fast and accurate calculation of scatter images by deterministically solving the LBTE thus offering a computationally attractive alternative to Monte Carlo methods. Part II describes the application of Acuros CTS to scatter correction of CBCT scans on the TrueBeam system.
