Effects of grid size and statistical uncertainty parameters on dose calculations using the Monte Carlo algorithm in the Monaco treatment planning system for liver stereotactic body radiotherapy.
Stereotactic body radiotherapy (SBRT) for liver metastases requires accurate dose calculation. The Monte Carlo (MC) algorithm in the Monaco treatment planning system (TPS) provides high dose-calculation accuracy; however, user-defined grid size (GS) and statistical uncertainty (SU) settings influence computational effi...
