TL;DR
The evaluated five DCAs include Monte Carlo algorithm employed by Monaco, pencil beam convolution and anisotropic analytical algorithms employed by Eclipse and Superposition, and Clarkson algorithms employed by PCRT3D TPSs had different levels of accuracy in TPSs.
Evaluated the accuracy of collapsed cone (CC) algorithm for dose calculation in the presence of lung inhomogeneity compared to the Monte Carlo (MC) algorithm as the reference and recommended increasing the minimum segment width to >0.5 cm in IMRT plans if CC algorithm is used.
The proposed framework improves dose prediction while incorporating physically meaningful priors into the learning process, offering a promising basis for PET-based dose-monitoring model development in CIRT.
Purpose: To develop and describe the architecture of a physical module for a Dose-Anatomical Planning System (DAPS) for ion beam therapy based on the GEANT4 platform, and to optimize its computational efficiency for clinical application under limited computing resources. Material and methods: Simulation of the interac...
This work establishes a robust, cross-validated computational baseline for brachytherapy dosimetry using general-purpose MC codes under realistic photon emission spectra under realistic, unsimplified photon emission spectra.
INTRODUCTION Numerous dosimetric studies have reported clinically insignificant differences between iridium-192 and cobalt-60. However, such comparison studies were conducted using TG-43 algorithms where heterogeneity is not accounted. Model based dose calculation algorithms (MBDCA) significantly improve dosimetric acc...
INTRODUCTION Unintended irradiation of organs outside the target volume remains a concern in pelvic radiotherapy, particularly for radiosensitive structures such as the gonads. Analytical dose calculation algorithms used in treatment planning systems (TPS) may underestimate out-of-field doses. Monte Carlo (MC) methods...
