| description | As the rate of death due to cancer is increasing in the world, the world is
paying much more attention to effective treatments for cancer. Teletherapy is
a type of treatment that delivers radiation to cancer cells from a specific
distance. The focus of this study is exclusively on Cobalt-60 teletherapy, which
has recently been installed at the Secondary Standard Dosimetry Laboratory
(SSDL) of the Bangladesh Atomic Energy Commission to provide quality
assurance and quality control services for all radiotherapy machines in
Bangladesh. Our objective is to conduct a series of measurements that are
necessary for the commissioning and acceptance of the installed Cobalt-60
machine (Equinox 100). The measurements include some mechanical
parameters, including the accuracy of a variety of indicators and the size of
the fields, before the measurement of dosimetry with two protocols, TRS-277
and TRS-398. We have found 0.16% deviation in the accuracy of optical
indicator, 0.04% deviation in the accuracy of collimator angle indicator and
0.06% deviation in the accuracy of field sizes throughout the study. We have
found no error in the accuracy of gantry indicator. In this work, the focus is
primarily on the mechanical calibration to ensure that a dosimetry plan that is
practical and accurate is being developed for the treatment of cancer patients.
The output of this study may contribute to the development of treatment
planning systems for cancer treatment. |
