Performance prediction of gamma electron vertex imaging (GEVI) system for interfractional range shift detection in spot scanning proton therapy

open access: yesNuclear Engineering and Technology, 2022
The maximum dose delivery at the end of the beam range provides the main advantage of using proton therapy. The range of the proton beam, however, is subject to uncertainties, which limit the clinical benefits of proton therapy and, therefore, accurate ...

Towards Laser Driven Hadron Cancer Radiotherapy: A Review of Progress [PDF]

open access: yes, 2014
It has been known for about sixty years that proton and heavy ion therapy is a very powerful radiation procedure for treating tumours. It has an innate ability to irradiate tumours with greater doses and spatial selectivity compared with electron and ...

The grid-dose-spreading algorithm for dose distribution calculation in heavy charged particle radiotherapy [PDF]

open access: yes, 2007
A new variant of the pencil-beam (PB) algorithm for dose distribution calculation for radiotherapy with protons and heavier ions, the grid-dose spreading (GDS) algorithm, is proposed.

On the accuracy of Monte Carlo based beam dynamics models for the degrader in proton therapy facilities

open access: yes, 2018
In a cyclotron-based proton therapy facility, the energy changes are performed by means of a degrader of variable thickness. The interaction of the proton beam with the degrader creates energy tails and increases the beam emittance.

Local treatment failure after globe-conserving therapy for choroidal melanoma. [PDF]

open access: yes, 2013
Local treatment failure after globe-conserving therapy for choroidal melanoma is a surgical complication with significant morbidity to the vision and eye. Few reports in the literature have addressed this complication exclusively.

Dosimetric evidence confirms computational model for magnetic field induced dose distortions of therapeutic proton beams

open access: yes, 2017
Given the sensitivity of proton therapy to anatomical variations, this cancer treatment modality is expected to benefit greatly from integration with magnetic resonance (MR) imaging.
