An Evaluation of The Consistency of Imrt Patient-Specific Qa Techniques
… 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 institutions, and many devices and action levels are used. Since the acceptance criteria …

Development of a Comprehensive Linac-based Quality Assurance Program for a Retrofitted Micro-MLC SRS System
… could be measured and add these tests to our patient specific QA, monthly QA, and annual QA procedures. A plastic phantom was constructed with holes drilled in each of the sides to meet at a common point in the middle of the phantom. This common intersection was then set as the isocenter for …
