ABSTRACT
Objective:
To set up the procedures of performance test and quality assurance of TruebeamTM by measuring the mechanical parameters, field parameters, imaging isocenter and respiratory gating systems.Methods:
Utilize level and graph paper to test the mechanical parameters; Utilize the film, 3D water tank and dosimeter to measure the corresponding field parameters;Utilize IsocCal phantom to test the shift of imaging isocenter and to use dosimeter to verify the beam on accuracy of respiratory gating systems.Results:
All of the tested mechanical parameters were within the tolerance. The coincidence of light field and radiation field was less than 1.2 mm. The flatness was less than 105%except for the flattening filter free beam and the symmetry was less than 102%. The absolute dose error was less than 1%. The shift of imaging isocenter was less than 3 mm and the dose error was within 0.5‰when the respiratory gating function was implemented.Conclusion:
TruebeamTM possesses superior mechanical performance and is very suitable to carry out complicated radiotherapy techniques.
