Timing of Annual Output Calibration of Radiotherapy Linear Accelerators
International Journal of Radiology and Radiation Oncology
Editorial
The output of radiotherapy Linear Accelerators (Linacs) is calibrated following national or international protocols like TG-51 by the American Association of Physicists in Medicine [1] or TRS- 398 by the International Atomic Energy Agency [2], annually on or before the anniversary date of the commissioning of each Linac. The anniversary dates fall at random times around the year. Is there a better time for annual output calibration than on random anniversary dates? In view of the recent report of seasonal output variation [3,4], it is time to consider performing annual output calibration in the months not having extreme air humidity.
