TL;DR: Analysis shows that incorporation of the organ motion could lead to changes in the dose prescribed for a treatment based on the Veff of the uninvolved liver, as per a liver dose escalation protocol in use at this institution.

TL;DR: This Review discusses the theoretical foundations of the development of acceleration methods for iterative convergence of discrete-ordinates simulations, the important results that have been accomplished, and remaining open questions.

TL;DR: In this article, a method for solving initial and boundary value problems for the energy dependent and one speed neutron transport equations is presented, which consists in constructing an asymptotic expansion of the neutron density ψ(r, v, τ) with respect to a small parameter e, which is the ratio of a typical mean free path of a neutron to a typical dimension of the domain under consideration.

TL;DR: In this article, a theoretical method is described for assessing the accuracy of transport differencing schemes in highly scattering media with optically thick spatial meshes and numerical results are presented that demonstrate the validity and accuracy of the analysis.

TL;DR: It is concluded that the simplified spherical harmonics methods can accurately model light propagation in small tissue geometries at visible and near-infrared wavelengths, yielding transport-like solutions with only a fraction of the computational cost of the transport calculation.
