Understanding setup of relative and absolute measurements for LINAC
(ELEKTA) on Radiation and Isotopes Center Khartoum (RICK) with the new
dosimetry equipments, acquired necessary and sufficient skills. The aims of
this study are: 1- commission the new linear accelerator and to understand
the dosimetry principle underlying, 2- to verify the acquired data with
published data such as British Journal of Radiology (BJR), supplementary 25,
3- to determine the absolute dose to the water using IAEA TRS 398 protocol.
Computerized water phantom (Blue Phantom) was used to achieve a
high accuracy and to gain the time during the measurements of the central
axis data of 6 MV for ELEKTA accelerator. The total uncertainty in the
determination of the dose to water during calculation of the beam was found
to be < 2.5 % and this magnitude within the accepted limits of
recommendation of the IAEA protocol ( 2.5%). The comparison of published
data of BJR and acquired data represents deviation of 1% in PDD and no any
deviation on TMR.
The maximum relative difference was achieved in the deviation of 1
mm on the maximum depth and the evaluation the reasons of theses
4
deviation was represented in this study. Investigation on the software of the
water phantom may need to be applied. |
