Evaluation of the dataset quality in gamma passing rate predictions using machine learning methods [PDF]
The British Journal of Radiology, 2023 Objective: Gamma passing rate (GPR) predictions using machine learning methods have been explored for treatment verification of radiotherapy plans. However, these methods presented datasets with unbalanced number of plans having different treatment conditions (heterogeneous datasets), such as anatomical sites or dose per fractions, leading to lower ...

Predictive gamma passing rate by dose uncertainty potential accumulation model [PDF]
Medical Physics, 2018 PurposeIntensity‐modulated radiation therapy (IMRT) utilizes many small fields for producing a uniform dose distribution. Therefore, there are many field junctions in the target region, and resulting dose uncertainties are accumulated. However, such accumulation of the dose uncertainty has not been implemented in the current practice of IMRT dose ...
