An experimental slope method for a more accurate measurement of relative radiation doses using radiographic and radiochromic films and its application to megavoltage small-field dosimetry

Autor: Raghavendra Holla, D Khanna, Bhaskaran K Pillai, K V Jafar Ali, P S Renil Mon, C O Clinto, Tharmarnadar Ganesh

Publikováno v: Journal of Medical Physics, Vol 44, Iss 3, Pp 145-155 (2019)

Purpose: An experimental method using the linear portion of the relative film dose–response curve for radiographic and radiochromic films is presented, which can be used to determine the relative depth doses in a variety of very small, medium, and

Malfunction of Linear Accelerator Dose Monitoring Systems

Autor: Karen P. Doppke, Richard G. Lane, Bhaskaran K. Pillai, Philip F. Judy

Publikováno v: Radiology. 115:734-735

Malfunctions of the dose monitoring systems of two linear accelerators were studied. A variation of plus or minus 2.5% over an air density correction factor range from 1.02 to 1.07 was measured, suggesting that the ionization-type monitor chambers we
