PURPOSE The aim of this work was to comprehensively evaluate a new large field ion chamber transmission detector, Integral Quality Monitor (IQM), for online external photon beam verification and quality assurance. The device is designed to be mounted on the linac accessory tray to measure and verify photon energy, field shape, gantry position, and fluence before and during patient treatment. METHODS Our institution evaluated the newly developed ion chamber's effect on photon beam fluence… CONTINUE READING
