Evaluation of the Delta4 phantom for IMRT and VMAT verification.
The Delta(4) diode array phantom (Scandidos, Uppsala, Sweden) was evaluated for verification of segmental intensity-modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) on an Elekta linear accelerator (Crawley UK). The device was tested for angular sensitivity by irradiating it from 36 different gantry angles, and the responses of the device to various step-and-shoot s...
متن کاملA Generalized Strategy for 3D Dose Verification of IMRT/VMAT Using EPID-measured Transit Images
The aim in this study is to develop a generalized strategy for 3D dose verification of IMRT and VMAT planes using EPID transit images in combination with Monte Carlo (MC) simulations. An EPID-based dosimetric verification procedure was developed to convert EPID-measured transit images into 2D exit photon fluence by de-convoluting with the MC-simulated EPID response kernels. The present scatter ...
متن کاملComparison of 3D anatomical dose verification and 2D phantom dose verification of IMRT/VMAT treatments for nasopharyngeal carcinoma
BACKGROUND The two-dimensional phantom dose verification (2D-PDV) using hybrid plan and planar dose measurement has been widely used for IMRT treatment QA. Due to the lack of information about the correlations between the verification results and the anatomical structure of patients, it is inadequate in clinical evaluation. A three-dimensional anatomical dose verification (3D-ADV) method was us...
متن کاملGuidelines for the Verification of Imrt Guidelines for the Verification of Imrt
V ACKNOWLEDGEMENTS When writing a booklet about a topic that is under rapid development such as the clinical introduction of an advanced treatment technique like IMRT, there is a chance that at the time of publication many solutions might already be obsolete or replaced by other approaches. We therefore greatly appreciate very much that we got the latest information from the participating centr...
