The aim of this study has been to develop a two-step method of in-phantom dosimetry around a brachytherapy 192 Ir photon source. The first step is to measure the absorbed dose rate to water with a calibrated ionization chamber under reference conditi

Purpose: The introduction of advanced treatment techniques in proton therapy, such as intensity-modulated proton therapy, leads to an increased need for patient-specific quality assurance, especially an accurate treatment plan verification becomes in

Internal scatter, the unavoidable major component of the peripheral dose in photon-beam radiotherapy

Physics in Medicine and Biology. 57:1733-1743
In clinical photon beams, the dose outside the geometrical field limits is produced by photons originating from (i) head leakage, (ii) scattering at the beam collimators and the flattening filter (head scatter) and (iii) scattering from the directly

A new concept for the design of flattening filters applied in the generation of 6 and 15 MV photon beams by clinical linear accelerators is evaluated by Monte Carlo simulation. The beam head of the Siemens Primus accelerator has been taken as the sta

In photon-beam radiotherapy, the absorbed dose in an irradiated object contains a contribution by energy-degraded photons originating from Compton scatter processes at parts of the treatment head and within the absorber itself. These low-energy spect
