Comprehensive Evaluations of Cone-beam CT dose in Image-guided Radiation Therapy via GPU-based Monte Carlo simulations
Davide Montanari, Enrica Scolari, Chiara Silvestri +6
Cone beam CT (CBCT) has been widely used for patient setup in image guided radiation therapy (IGRT). Radiation dose from CBCT scans has become a clinical concern. The purposes of t…
GPU-based Monte Carlo radiotherapy dose calculation using phase-space sources
Reid Townson, Xun Jia, Zhen Tian +3
A novel phase-space source implementation has been designed for GPU-based Monte Carlo dose calculation engines. Due to the parallelized nature of GPU hardware, it is essential to s…
Effect of Statistical Fluctuation in Monte Carlo Based Photon Beam Dose Calculation on Gamma Index Evaluation
Yan Jiang Graves, Xun Jia, Steve B. Jiang
The gamma-index test has been commonly adopted to quantify the degree of agreement between a reference dose distribution and an evaluation dose distribution. Monte Carlo (MC) simul…
Optimal Surface Marker Locations for Tumor Motion Estimation in Lung Cancer Radiotherapy
Bin Dong, Yan Jiang Graves, Xun Jia +1
Using fiducial markers on patient's body surface to predict the tumor location is a widely used approach in lung cancer radiotherapy. The purpose of this work is to propose an algo…
GPU-based fast Monte Carlo simulation for radiotherapy dose calculation
Xun Jia, Xuejun Gu, Yan Jiang Graves +2
Monte Carlo (MC) simulation is commonly considered to be the most accurate dose calculation method in radiotherapy. However, its efficiency still requires improvement for many rout…
