First time in Coimbatore and second in Tamil Nadu is used ocular BT treatment for choroidal melanoma and delivers a highly concentrated radiation dose to the tumor (with relatively less radiation to surrounding healthy tissues) Brachy therapy is a technique where the radioactive sources are placed into or close to the tumour resulting in a high dose delivered to the tumour than the surrounding tissue. High dose rate brachytherapy is radio biologically proven to be as effective as low dose rate. As these machines are remote after-loading type, exposure to the radiation personnel is minimum. As this system is computer controlled, precise planning and optimization is possible. It is used in treatment of cancers of Bronchus esophagus, breast and cervix commonly.
