Abstract EN
Deterministic linear Boltzmann transport equation (D-LBTE) solvers have recently been developed, and one of the latest available software codes, Acuros XB, has been implemented in a commercial treatment planning system for radiotherapy photon beam dose calculation.
One of the major limitations of most commercially available model-based algorithms for photon dose calculation is the ability to account for the effect of electron transport.
This induces some errors in patient dose calculations, especially near heterogeneous interfaces between low and high density media such as tissue/lung interfaces.
D-LBTE solvers have a high potential of producing accurate dose distributions in and near heterogeneous media in the human body.
Extensive previous investigations have proved that D-LBTE solvers were able to produce comparable dose calculation accuracy as Monte Carlo methods with a reasonable speed good enough for clinical use.
The current paper reviews the dosimetric evaluations of D-LBTE solvers for external beam photon radiotherapy.
This content summarizes and discusses dosimetric validations for D-LBTE solvers in both homogeneous and heterogeneous media under different circumstances and also the clinical impact on various diseases due to the conversion of dose calculation from a conventional convolution/superposition algorithm to a recently released D-LBTE solver.
