Proposal of a Novel Setup for Linac Monitoring Using a Specifically Designed Plastic Scintillator and a Spectrophotometer
Journal Title: Journal of Nuclear Physics, Material Sciences, Radiation and Applications - Year 2016, Vol 4, Issue 1
Abstract
In this work, we report the design, implementation, and results of an alternative monitoring system for a linear accelerator (LINAC) used in medical therapy. The system proposed consist in as lab of scintillator plastic with a wavelength shifter fiber-optically coupled to collect the light generated, and a Spectrophotometer Ocean Optics USB4000 as analyzer. The control was made with two computers, one into the therapy room and another, using a VNC (Virtual Network Computer) and Ethernet wire, outside of the room in order to avoid radiation exposure. The LINAC dose range covered was 1, 2, 3, 4, 5, 10, 20, 30 and 40 Monitor Units (MU) with 6 and 18 MeV energy photons. The spectrum obtained was compared with the measures of the LINAC ionization camera used to calibrate it. The results obtained allow us to propose this device as an alternative method to monitor the LINAC performance.
