Assessment of out‐of‐field absorbed dose and equivalent dose in proton fields [PDF]
Medical Physics, 2009 PurposeIn proton therapy, as in other forms of radiation therapy, scattered and secondary particles produce undesired dose outside the target volume that may increase the risk of radiation‐induced secondary cancer and interact with electronic devices in the treatment room.

Electron Streaming Effect Associated With the Elekta Unity Anterior Imaging Coil
Frontiers in Physics, 2022 The presence of the static field in magnetic resonance guided radiation therapy (MRgRT) systems, such as the Elekta Unity MR-Linac (MRL), influences charged particle motion due to the Lorentz force in and around patients.

Issues arising from the HASTE experiments [PDF]
, 2005 [FIRST PARAGRAPH] The HASTE project work discussed in the foregoing papers can be depicted as being aimed at answering two questions: “Does greater secondary task load from an In-Vehicle Information System (IVIS) lead to an identifiably worse ...

A publicly available dataset of out-of-field dose profiles of a 6 MV linear accelerator [PDF]
Physical and Engineering Sciences in Medicine, 2021 Abstract An increase in radiotherapy-induced secondary malignancies has led to recent developments in analytical modelling of out-of-field dose. These models must be validated against measurements, but currently available datasets are outdated or limited in scope.
