Timing of Annual Output Calibration of Radiotherapy Linear Accelerators

Murshed Hossain*

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.
