The Advanced Centre for Treatment Research and Education in Cancer (ACTREC) has installed dual purpose hi-tech TomoTherapy system, a first of its kind in India.“This is a a revolutionary technology for image-guided Intensity Modulated Radiation Therapy (IMRT). The TomoTherapy has broad applicability in a wide variety of cancers with a potential to improve outcome, said Dr S Banerjee, Director, Bhabha Atomic Research Centre on Saturday. It is used for imaging as well as precise treatment of cancer. It combines inverse planning, CT-guided patient positioning, and IMRT into one integrated system for enhanced precision in planning and delivery, Banerjee said while elaborating the science and mathematics behind it. ACTREC is a unit of the Department of Atomic energy. Speaking on the occasion, the US-based TomoTherapy Inc President and co-founder Paul Reckwerdt said this novel machine has been delivered to 28 countries. It has a wide range of precision energy delivery in cancer treatment and has not shown any kind of side effects during and after treatment, he said.
