Conventional Linear Accelerators (Linac) are the major workforce machines in radiation oncology. The functionalities and performances of Linac are set at the time of initial installation. Acceptance testing (AT) is important to check the satisfactory fulfill of the contractual specifications. Many technical details of Linac performance at acceptance testing will be used as baselines for ongoing routine Quality Assurance. This session will discuss the technical specifications of the AT tests, AT process and failure modes and also the details included in the purchase contract. We will provide definition of performance specifications for major LINAC subsystems in acceptance testing procedures including Imaging components, special procedure components such as Stereotactic RadioSurgery (SRS) cones and micro Multiple Leaf Collimator (MLC) etc. We will make recommendations on the tests to be performed during the LINAC acceptance testing procedure. Also the emphasis would also be given on quantitative collection of relevant data during AT for periodic QA along several image based automated tests that are being performed during AT. Finally recommended responsibility of Vendor in commissioning process would be discussed.
Learning Objectives:
1. To learn the details of technical specifications in the AT test.
2. To understand the tests to be performed at acceptance testing and also AT process
3. To learn testing methods that complement vendor-suggested measurements for beam matching and subsequent major repair/upgrades
4. Automated tests and Quantitative data that should be provided during AT for facilitating ongoing QA & upgraded.
5. Maximizing the overlap of AT and Commissioning process.
