QUALITY CONTROL PERFORMANCE ANALYSIS WITH THE MACHINE PERFORMANCE CHECK SOFTWARE TO CHECK THE VITALBEAM LINEAR ACCELERATOR

Abstract

The development of irradiation techniques based on medical accelerators requires the development of new and more effective quality control programs that would take into account changes in the designs of accelerators and their output devices. Since quality control is an indispensable process for evaluating the functional characteristics of the accelerator, this work is devoted to the study of the effectiveness of procedures using Machine Performance Check. Test checks are shown along with standard procedures. This analysis revealed the need to use MPC for quality control of linear accelerators. MPC application is used to verify the geometry and beam characteristics of linear accelerators using automated checks based on their kV-MV imaging systems. Radiation therapy using linear accelerators requires extensive knowledge of the positioning accuracy of the multi-petal collimator flaps. In this study, preliminary tests with MPC were analyzed using all the energies of the VitalBeam photon beam.
