Dosimetric comparison of different dose calculation algorithms in postmastectomy breast cancer patients using conformal planning techniques

Journal of Medical Physics, 2023
Background: The aim of the current study was to compare three different dose-calculating algorithms, i.e., superposition (SP), fast SP (FSP), and convolution (CV), for breast cancer patients treated with intensity-modulated radiotherapy (IMRT) and field ...

Monitor units are not predictive of neutron dose for high-energy IMRT

Radiation Oncology, 2012
Background Due to the substantial increase in beam-on time of high energy intensity-modulated radiotherapy (>10 MV) techniques to deliver the same target dose compared to conventional treatment techniques, an increased dose of scatter radiation ...

Intensity-modulated Radiotherapy for the Treatment of Breast Cancer [PDF]

Clinical Oncology, 2013
In the systematic review of intensity-modulated radiotherapy (IMRT) in the treatment of breast cancer reported in Clinical Oncology by Dayes and colleagues [1], the only prospective randomised clinical trial (n = 306) testing forward-planned IMRT to have reported a 5 year outcome for adverse effects [2] was excluded on the spurious grounds that no ...

Advances in Intensity-Modulated Radiotherapy Delivery

, 2008
Fixed-field intensity-modulated treatments, delivered by conventional linac-plus-multileaf systems, have rapidly become the most common form of IMRT. Several innovative alternative IMRT options are also now available, including tomotherapy, CyberKnife and jaws-only linacs. These innovative approaches have divergent rationales.

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.
