Evaluation of IMRT QA Point Measurement Rocesses Using a Commercial Heterogeneous Phantom
Lung cancer is the leading cause of cancer mortality in the United States. Significant effort has been carried out in developing highly conformal dose delivery techniques using multiple coplanar beams for these patients. IMRT is being used for lung cancer treatment and has shown the potential to deliver a highly conformal dose to the target while minimizing dose to the healthy tissues and is th...
متن کاملDose calculations accuracy of TiGRT treatment planning system for small IMRT beamlets in heterogeneous lung phantom
Background: Accurate dose calculations in small beamlets and lung material have been a great challenge for most of treatment planning systems (TPS). In the current study, the dose calculation accuracy of TiGRT TPS was evaluated for small beamlets in water and lung phantom by comparison to Monte Carlo (MC) calculations. Materials and Methods: The head of Siemens Oncor-impression linac...
متن کاملInvestigation of error detection capabilities of phantom, EPID and MLC log file based IMRT QA methods
A patient specific quality assurance (QA) should detect errors that originate anywhere in the treatment planning process. However, the increasing complexity of treatment plans has increased the need for improvements in the accuracy of the patient specific pretreatment verification process. This has led to the utilization of higher resolution QA methods such as the electronic portal imaging devi...
متن کاملIMRT QA using machine learning: A multi‐institutional validation
PURPOSE To validate a machine learning approach to Virtual intensity-modulated radiation therapy (IMRT) quality assurance (QA) for accurately predicting gamma passing rates using different measurement approaches at different institutions. METHODS A Virtual IMRT QA framework was previously developed using a machine learning algorithm based on 498 IMRT plans, in which QA measurements were perfo...
متن کاملComparison of 2D and 3D Gamma calculations for an IMRT QA phantom
Gamma index pass rates were evaluated for an anthropomorphic phantom using both 2D and 3D calculations. The phantom was irradiated with the traditional dosimetry insert loaded with radiochromic film and TLD, and then with a 3D dosimetry insert. A comparison with the calculated dose distribution showed that both the PRESAGE ® dosimeter and the film and TLD system agreed with the plan to within 5...
