Exploratory analysis using machine learning to predict for chest wall pain in patients with stage I non-small-cell lung cancer treated with stereotactic body radiation therapy. [PDF]

, 2018
Background and purposeChest wall toxicity is observed after stereotactic body radiation therapy (SBRT) for peripherally located lung tumors. We utilize machine learning algorithms to identify toxicity predictors to develop dose-volume constraints ...

Preclinical dose assessment of cyberknife with small animal intracranial irradiation using a 3D printed mouse phantom

Scientific Reports
Dose verification in preclinical CyberKnife-based stereotactic radiosurgery (CK-SRS) of intracranial tumors is complicated by the unique characteristics of the system, including its highly conformal, non-coplanar radiation delivery and small-field ...

Dependence of the thermoluminescent high-temperature ratio (HTR) of LiF:Mg,Ti detectors on proton energy and dose

, 2014
The high-temperature ratio (HTR) is a parameter quantifying changes of the shape of the high-temperature part of the LiF:Mg,Ti glow-curve after exposure to densely ionizing radiation. It was introduced in order to estimate the effective LET of an unknown
