The Swiss IMRT dosimetry intercomparison using a thorax phantom.
PURPOSE In 2008, a national intensity modulated radiation therapy (IMRT) dosimetry intercomparison was carried out for all 23 radiation oncology institutions in Switzerland. It was the aim to check the treatment chain focused on the planning, dose calculation, and irradiation process. METHODS A thorax phantom with inhomogeneities was used, in which thermoluminescence dosimeter (TLD) and ioniz...
متن کاملExperimental evaluation of midline dose calculation methods in In vivo dosimetry using anatomic thorax phantom
Background: In vivo dosimetry is a method for estimation of overall error in the delivered dose to the patients at the end of radiotherapy process. In this research, two methods for target dose calculation were evaluated on midline and central axis of photon beams in in vivo dosimetry of thorax fields. Materials and Methods: Entrance and exit doses for anterior and lateral fields of thorax were...
متن کاملExperimental evaluation of midline dose calculation methods in In vivo dosimetry using anatomic thorax phantom
Accuracy in the delivered dose to the patients plays an important and vital role in radiotherapy treatments. This happens because of steep gradient of dose-local control and dose-normal tissue complication probability curves. Dosimetric uncertainty of 3%-4% (one standard deviation) in the delivered dose to the target volume as an acceptable level has been recommended(1-3). In many centers, in v...

متن کاملInvestigating the Feasibility of 3D Dosimetry in the RPC IMRT H&N Phantom.
An urgent requirement for 3D dosimetry has been recognized because of high failure rate (~25%) in RPC credentialing, which relies on point and 2D dose measurements. Comprehensive 3D dosimetry is likely to resolve more errors and improve IMRT quality assurance. This work presents an investigation of the feasibility of PRESAGE/optical-CT 3D dosimetry in the Radiologic Physics Center (RPC) IMRT H&...
