Final Presentation	02/09/2019 Progress Report Outline: Introduction to Proton beam therapy. What is Quality Assurance? Important beam characteristics. Commercially available devices such as the Matrixx, Lynx and Sun Nuclear QA3. Other methods for measuring beam properties. Comments made about presentation: Understand what range modulators do. Look into whether Zebra was initially designed for X-Rays. Zebra not often used for daily QA due to the very long initial set up time. Investigate film dosimetry e.g Gafchromic film. Research Lynx scintillator. Range calorimeter - need a moving absorber, e.g water tank, to measure energy and range. Know difference between scintillator screens and fibres - fibres use fibre optics and are not used due to needing something to read output from each fibre which is expensive. UCLH will have 4 treatment rooms. Put slide number on presentation. Expand on each daily QA: Table of devices Tolerances How long it takes Collect standards and tolerances on energy, spot size and output.
