Out‐of‐field doses and neutron dose equivalents for electron beams from modern Varian and Elekta linear accelerators [PDF]
Journal of Applied Clinical Medical Physics, 2016 Out‐of‐field doses from radiotherapy can cause harmful side effects or eventually lead to secondary cancers. Scattered doses outside the applicator field, neutron source strength values, and neutron dose equivalents have not been broadly investigated for

Validation of Monte Carlo Model for Dose Evaluation outside the Treatment Field for Siemens 6MV Beam [PDF]
Iranian Journal of Medical Physics, 2020 Introduction: There has been a concern about the unintended doses to critical structures outside the treatment field due to the increased risk of radiation-induced second cancer following radiotherapy treatments.

Out-of-field dose equivalents delivered by proton therapy of prostate cancer.
Medical Physics, 2007 Measurements were performed to assess the dose equivalent outside a primary proton treatment field, using a silicon‐on‐insulator (SOI) microdosimeter. The SOI microdosimeter was placed on the surface of an anthropomorphic phantom and dose equivalents were determined as a function of lateral distance from a typical passively scattered and modulated ...

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.

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.
