Timing of Annual Output Calibration of Radiotherapy Linear Accelerators Murshed Hossain<p>The output of radiotherapy Linear Accelerators (Linacs) is calibrated&nbsp; following&nbsp; national&nbsp; or&nbsp; international&nbsp; protocols&nbsp; like TG-51 by&nbsp; the&nbsp; American Association&nbsp; of&nbsp; Physicists&nbsp; in&nbsp; Medicine&nbsp; [1] or&nbsp; TRS-398 by the International Atomic Energy Agency [2], annually on or before the anniversary date of the commissioning of each Linac.The anniversary&nbsp; dates fall&nbsp; at&nbsp; random&nbsp; times&nbsp; around&nbsp; the&nbsp; year.&nbsp; Is&nbsp; there&nbsp; 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&nbsp; is&nbsp; time&nbsp; to&nbsp; consider&nbsp; performing&nbsp; annual&nbsp; output&nbsp; calibration&nbsp; in&nbsp; the months not having extreme air humidity.</p> International Journal of Radiology and Radiation Oncology - Peertechz Publications 2016-01-23 Editorial https://doi.org/10.17352/ijrro.000011 en Copyright © Murshed Hossain et al.
