Out of Field Doses in Clinical Photon and Proton Beam

AIP Conference Proceedings, 2010
Out‐of‐field doses in homogenous cubical polymethylmethacrylate (PMMA) phantom were studied in this work. Measurements were performed in clinical 171 MeV proton and megavoltae photon beam. As detectors, CaSO:Dy thermoluminescent detectors were used. According to expectancy, results showed that out‐of‐field doses are substantially lower for clinical ...

Out-of-field doses in radiotherapy: Input to epidemiological studies and dose-risk models

Physica Medica, 2017
Out-of-field doses in radiotherapy have been increasingly studied in recent years because of the generally improved survival of patients who have received radiotherapy as part of their treatment for cancer and their subsequent risk of a second malignancy.

Poster — Thur Eve — 36: Out‐of‐Field dose in craniospinal irradiation

Medical Physics, 2012
The risk of radiotherapy induced secondary cancer depends on the integral dose delivered to the patient where the dose delivered within the radiation field is accounted for, as well as dose to out‐of‐field organs from scattered and leakage radiation.

Out-of-field dose measurements for radiotherapy of brain tumours in paediatric patients

Physica medica, 2014
It has been known for many years that out-of-field radiation doses to normal tissues may be associated with an increased risk of secondary cancers. Paediatric patients are of particular concern due to their possible longer life expectancy and higher organ radiosensitivities compared with adult patients and higher organ doses because of their smaller ...

Out-of-field dose measurements in radiotherapy

2011
This thesis describes the results from measurements of the out-of-field dose in radiotherapy. The dose outside the treatment volume has been determined in a water phantom and an anthropomorphic phantom. Measurements were performed with linac photons, passively delivered protons, scanned protons, passively delivered carbon ions as well as scanned carbon

Calculation of out‐of‐field dose distribution in carbon‐ion radiotherapy by Monte Carlo simulation

Medical Physics, 2012
Purpose:Recent radiotherapy technologies including carbon‐ion radiotherapy can improve the dose concentration in the target volume, thereby not only reducing side effects in organs at risk but also the secondary cancer risk within or near the irradiation field.
