Quality assurance is an important part of the radiation treatment program. It is not a static program and must develop to keep on track with developing technologies. More specifically, the speakers in this session will examine the changes in three areas that have been under recent development.
Firstly, 3D printing has allowed rapid prototyping of clinical and QA equipment that would have taken years to develop previously. The development and manufacture of these devices will be examined.
Secondly, the application of IAEA-AAPM TRS-483 for Co-60 based SRS/SBRT systems. New technology continues to be developed for SRS treatments, including a novel Co-60 based system for breast radiation therapy. Speakers in this session will present various techniques for reference-dosimetry measurements with a new Co-60 SRS breast therapy device.
Lastly, SRS/SBRT techniques require that the mechanical stability of linacs and the accuracy of image guidance systems be checked with high precision. A revival of the Winston-Lutz test to improve linac QA in the digital age will be presented.
Learning Objectives:
1. How develop in in house QA program to QA in-house developed treatment equipment
2. Brief review the application of TRS 483 in SRS
3. Learn how to implement digital Winston-Lutz test for radiation isocenter and image center QA.
