Quality assurance devices for dynamic conformal radiotherapy
Two quality control devices, light-field device and radiation-field device, have been specially designed to facilitate the clinical implementation of conformal dynamic arc treatment (CDAT) and intensity modulated radiation therapy (IMRT). With the devices, the light field as well as the radiation field, projected from the individual beam at any treatment position (i.e. arbitrary gantry angle) c...
متن کاملQuality assurance in conformal radiotherapy: DYNARAD consensus report on practice guidelines.
BACKGROUND AND PURPOSE Conformal radiotherapy has only recently been widely implemented. Although not all aspects have yet been adequately proven, it is generally recognized that maintaining a high degree of precision throughout the process is critical to the treatment outcome while the focus for quality assurance and quality improvement will need to concentrate more on human factors, procedure...
متن کاملdimensional film dosimetry with GAFCHROMIC films for quality assurance and dosimetric verification of 3D conformal radiotherapy in the presence of heterogeneities
Introduction: The presence of heterogeneities such as air-filled cavities in the head and neck treatment fields region, may result in potential dosimetric disagreement because the losses of charged particle equilibrium. Most of treatments planning systems are not able to predict dose distribution of inhomogeneities region accurately. Therefore, dose calculation algorithms need to...
متن کاملDosimetric Study of an Indigenous and Heterogeneous Pelvic Phantom for Radiotherapy Quality Assurance
Introduction: In vitro dosimetric verification prior to patient treatment plays a key role in accurate and precision radiotherapy treatment delivery. Since the human body is a heterogeneous medium, the aim of this study was to design a heterogeneous pelvic phantom for radiotherapy quality assurance. Material and Methods: A pelvic phantom was ...
متن کاملQuality Assurance of External Beam Radiotherapy
'Quality assurance' is all those planned and systematic actions necessary to provide adequate confidence that a product or service will satisfy the given requirements for quality (ISO 9000:1994). As such it is wide ranging, covering all relevant procedures, activities and actions, and hence all groups of staff involved in the process under consideration. 12.1.1.2. Quality assurance in radiother...
