Purpose: The primary fluence of a proton pencil beam exiting the accelerator is enveloped by a region of secondaries, commonly called “spray”. Although small in magnitude, this spray may affect dose distributions in pencil beam scanning mode e.g.

BackgroundIn radiotherapy, especially when treating children, minimising exposure of healthy tissue can prevent the development of adverse outcomes, including second cancers. In this study we propose a validated Monte Carlo framework to evaluate the

Proton therapy enables to deliver highly conformed dose distributions owing to the characteristic Bragg peak and the finite range of protons. However, during proton therapy, secondary neutrons are created, which can travel long distances and deposit

This experimental study investigates the radioactivation of titanium during proton therapy. Titanium is a commonly used material for implants. Because of its fixed position, the activation of those implants might be useful for post-irradiation field.

Objective. The lateral dose fall-off in proton pencil beam scanning (PBS) technique remains the preferred choice for sparing adjacent organs at risk as opposed to the distal edge due to the proton range uncertainties and potentially high relative bio

This experimental study aims to measure nuclear cross sections from natC and 27Al which serve as reference targets regarding radioactivation in proton therapy. Graphite and aluminum foils were activated in broad, quasi-monochromatic proton fields gen

In this work, we present measurements of nuclear activation cross sections from carbon. Carbon can be used for proton fluence calculation in proton therapy by measurements of the activity after irradiation. The cross sections are measured on a high-p
