Towards automated dose‐guided patient positioning at clinical timescale in head‐and‐neck cancer proton radiotherapy

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background In intensity modulated proton therapy (IMPT) accurate patient positioning prior to treatment delivery is important to ensure that the prescribed dose is delivered as intended. Typically, in‐room 3D imaging is utilized to position the patient based on anatomical features, which can be challenging due to interfractional anatomical ...

RBE of thermal neutrons for induction of chromosome aberrations in human lymphocytes [PDF]

, 2013
The induction of chromosome aberrations in human lymphocytes irradiated in vitro with slow neutrons was examined to assess the maximum low-dose RBE (RBE(M)) relative to (60)Co γ-rays.

Integrating microdosimetric in vitro RBE models for particle therapy into TOPAS MC using the MicrOdosimetry-based modeliNg for RBE ASsessment (MONAS) tool [PDF]

Objective. In this paper, we present MONAS (MicrOdosimetry-based modelliNg for relative biological effectiveness (RBE) ASsessment) toolkit. MONAS is a TOPAS Monte Carlo extension, that combines simulations of microdosimetric distributions with ...

Why RBE must be a variable and not a constant in proton therapy [PDF]

, 2016
Purpose: This paper considers why the proton therapy relative biological effect (RBE) should be variable rather than constant. Methods: The reasons for a variable proton RBE are enumerated, with qualitative and quantitative arguments.

Evaluation of organ-specific relative biological effectiveness of proton therapy using radiation-induced pneumonitis as an endpoint

Clinical and Translational Radiation Oncology
Background and purpose: Proton therapy has become widely used for non-small cell lung cancer (NSCLC) due to its ability to spare normal tissue. However, the commonly assumed relative biological effectiveness (RBE) of 1.1 may underestimate the therapy’s ...

Towards incorporation of RBE uncertainty in proton therapy planning systems [PDF]

, 2019
Current arguments concerning the variability of RBE in treatment plans are reviewed and cases are discussed where proton therapy may require the use of treatment planning systems in which a variable RBE is implemented.
