| dc.description.abstract | Modern radiotherapy facilities like 3-Dimensional conformal radio therapy
(3DCRT), Intensity Modulated Radiotherapy (IMRT), were recently suggested in
Co-60 machine with Multi-leaf Collimator (MLC). In this study, two reference
chambers NE-2571#1205 and NE2581#537 were used for absolute dose
measurement in Equinox accelerator. A comparison of dose measurement by two
different IAEA protocols TRS-277 and TRS-398 has been studied. Analyzing TRS-
398, a common shaped empirical formula was developed for the four Co-60 units of
four Medical Colleges in Bangladesh with fitting parameters. It was found that an
average discrepancy in the determination of absorbed dose in water among the two
different protocols TRS-277 and TRS-398 were 1.33 % for the chamber NE-
2571#1205 and 0.65 % for the chamber NE2581#537 with combined uncertainty
±1.59 % (k=1). A good convergence has been obtained in the concepts and methods
in this study. | en_US |
