COMP Report: Patient-specific quality assurance practices in Canadian radiotherapy-results from a national survey. [PDF]

J Appl Clin Med Phys
Abstract Patient‐specific quality assurance (PSQA) is an essential component of modern radiotherapy, ensuring safe and accurate delivery of increasingly complex treatments. Given its resource‐intensive nature and the availability of evolving approaches, examining how PSQA is implemented and optimized across Canada is important to inform best practices.

Proton beam therapy in paediatric cancer: Anticipating the opening of the Australian Bragg Centre for Proton Therapy and Research

Journal of Medical Imaging and Radiation Oncology, EarlyView., 2023
Summary Proton Beam Therapy (PBT) has the potential to improve paediatric cancer care by reducing radiation exposure and thus long‐term toxicities. Ethical concerns and debates surrounding the treatment, such as eligibility and accessibility, are ongoing in Australia. The Australian Bragg Centre for Proton Therapy and Research (ABCPTR) (named after Sir

Establishment of criteria for gamma-analysis of individual dose distributions during verification of radiotherapy high-tech treatment plans for cancer patients

Весці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2022
A typical process for verification of treatment plans in intensity-modulated radiation therapy is described. The main errors and uncertainties that arise in the course of planning dose distribution and in the process of dose delivery are listed.

Dosimetric Comparison between High Dose Rate Brachytherapy Boost and Volumetric Arc Therapy Boost in Locally Advanced Cancer Cervix

Asian Journal of Oncology, 2021
Concurrent chemoradiotherapy is considered the standard treatment for the locally advanced cancer cervix (LACC). Radiotherapy is commonly administered by a three-dimensional conformal radiotherapy (3DCRT) approach followed by brachytherapy (BT).

Multicriteria optimization informed VMAT planning [PDF]

Medical Dosimetry, 2014
We developed a patient-specific volumetric-modulated arc therapy (VMAT) optimization procedure using dose-volume histogram (DVH) information from multicriteria optimization (MCO) of intensity-modulated radiotherapy (IMRT) plans. The study included 10 patients with prostate cancer undergoing standard fractionation treatment, 10 patients with prostate ...

Automatic feathering algorithm for VMAT craniospinal irradiation: a comprehensive comparison with other VMAT planning strategies [PDF]

Physica Medica, 2021
In craniospinal irradiation, field matching is very sensitive to intrafraction positional uncertainties in cranio-caudal direction, which could lead to severe overdoses/underdoses inside the planning target volume. During the last decade, significant efforts were made to develop volumetric-modulated arc therapy strategies, which were less sensitive to ...

Transition from 3D conformal to modern modulated craniospinal radiotherapy

South African Journal of Oncology, 2022
Background: Achieving optimal tumour coverage during craniospinal irradiation (CSI) is a challenge. Whilst several critical organs are at risk of radiation-induced toxicity, if target volume structures like the cribriform plate receive less than 95% of ...
