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

Risk of second primary cancer from proton arc therapy of pediatric brain tumors
Physics and Imaging in Radiation Oncology, 2023 Proton arc therapy (PAT) is currently explored for clinical implementation, despite its associated low-dose bath. This study therefore aimed at evaluating the risk of radiation-induced second primary cancer (SPC) for PAT in pediatric brain tumor patients.

A comprehensive formulation for volumetric modulated arc therapy planning [PDF]
Medical Physics, 2016 Purpose:Volumetric modulated arc therapy (VMAT) is a widely employed radiation therapy technique, showing comparable dosimetry to static beam intensity modulated radiation therapy (IMRT) with reduced monitor units and treatment time. However, the current VMAT optimization has various greedy heuristics employed for an empirical solution, which ...

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 ...

Volumetric Modulated Arc Therapy for Advanced Pancreatic Cancer [PDF]
Strahlentherapie und Onkologie, 2010 Intensity-modulated radiotherapy (IMRT) allows for improved sparing of organs at risk (OARs) in advanced pancreatic cancer. A planning study evaluated if volumetric modulated arc therapy (RapidArc [RA]) could be used as an alternative to IMRT in such cases.In ten patients, five-field IMRT (5f-IMRT) plans with fixed gantry positions were compared to RA ...

Evaluation of volumetric modulated arc therapy for postmastectomy treatment [PDF]
Radiation Oncology, 2014 To examine the feasibility of volumetric modulated arc therapy (VMAT) for post mastectomy radiotherapy (PMRT).Fifteen PMRT patients previously treated at our clinic with helical tomotherapy (HT) were identified for the study. Planning target volumes (PTV) included the chest wall and regional lymph nodes.
