Comprehensive Calculation-Based Imrt Qa Using R&V Data, Treatment Records, and A Second Treatment Planning System
… </strong>Traditional patient-specific IMRT QA measurements are labor intensive and consume machine time. Calculation-based IMRT QA methods typically are not comprehensive. We have developed a comprehensive calculation-based IMRT QA method to detect uncertainties introduced by the …

An Evaluation of The Consistency of Imrt Patient-Specific Qa Techniques
… of an intensity modulated radiation therapy (IMRT) treatment, each plan must be validated through a measurement-based quality assurance (QA) procedure, known as patient specific IMRT QA. Many methods of measurement and analysis have evolved for this QA. There is not a standard among clinical …

Implementation of Upright Treatments For Lung and Head and Neck Cancers
… end-to-end test, the treatment plan passed the IMRT QA criteria of 0.95-1.05 for point dose and obtained a gamma index of 89.25%. Dosimetry verification demonstrated good agreement between the treatment plan doses and the delivered doses and obtained a point-dose dose difference of 2% and gamma …

Quality Assurance of Advanced Treatment Modalities Using Presage® Dosimeters
… plan should be included in patient-specific IMRT QA. A volumetric dosimeter such as PRESAGE<sup>®</sup> is able to provide a complete 3D measured dosimetry dataset with one treatment plan delivery. It was hypothesized that a PRESAGE<sup>® </sup>dosimeter would agree with 2D measurements …
