Proton beam therapy in the management of skull base chordomas: systematic review of indications, outcomes, and implications for neurosurgeons [PDF]

, 2016
BACKGROUND: Chordomas are rare tumours affecting the skull base. There is currently no clear consensus on the post-surgical radiation treatments that should be used after maximal tumour resection.

The physics of proton therapy

Physics in Medicine and Biology, 2015
The physics of proton therapy has advanced considerably since it was proposed in 1946. Today analytical equations and numerical simulation methods are available to predict and characterize many aspects of proton therapy. This article reviews the basic aspects of the physics of proton therapy, including proton interaction mechanisms, proton transport ...

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

, 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.

Monitoring of hadrontherapy treatments by means of charged particle detection [PDF]

, 2016
The interaction of the incoming beam radiation with the patient body in hadrontherapy treatments produces secondary charged and neutral particles, whose detection can be used for monitoring purposes and to perform an on-line check of beam particle ...

Transplantable melanomas in hamsters and gerbils as models for human melanoma : sensitization in melanoma radiotherapy : from animal models to clinical trials [PDF]

, 2018
The focus of the present review is to investigate the role of melanin in the radioprotection of melanoma and attempts to sensitize tumors to radiation by inhibiting melanogenesis. Early studies showed radical scavenging, oxygen consumption and adsorption

Comparison of pencil beam and Monte Carlo calculations with ion chamber array measurements for patient-specific quality assurance

Radiation Medicine and Protection, 2022
Objective: To determine under what conditions and criteria comparisons between calculations made with the current clinical treatment planning system (Syngo) and an in-house built TPS (TIMPS) would allow skipping of in-beam portal-specific measurements ...

Comparative clinical evaluation of atlas and deep-learning-based auto-segmentation of organ structures in liver cancer

Radiation Oncology, 2019
Background Accurate and standardized descriptions of organs at risk (OARs) are essential in radiation therapy for treatment planning and evaluation. Traditionally, physicians have contoured patient images manually, which, is time-consuming and subject to

Development of a Comprehensive, Contour-Based, Peer Review Workflow at a Community Proton Center [PDF]

International Journal of Particle Therapy, 2020
Purpose: Quality assurance and continuing quality improvement are integral parts of any radiation oncology practice. With increasingly conformal radiation treatments, it has become critical to focus on every slice of the target contour to ensure adequate
