Abstract:
The procedures for the calculation and measurement and calibration of output dose of the Siemens primus E accelerator with IAEA regulation are introduced to probe an accurate,rapid and effective method.The parameter value of measurement is determined according to IAEA regulations and absorbed dose calculation formal is briefed to the form that the reading of instrument multiplies exposure calibration coefficient Nx and Air temperature,pressure and humidity effects Ktp and cumulative correction factor Cf the precision of accelerator conform to the standard of QA&QC by the measurement and calibration of the Hospital Primus E accelerator in output dose.The methods of measurement and calibration can be used for the determination of output dose in precise radiotherapy of digital medical linear accelerator and clinical treatment.
