The Department is responsible for Treatment Planning of all cancer patients in Radiation Oncology. The routine work includes conventional, conformal, Intensity Modulated Radiation Therapy, RapidArc treatment and SBRT planning as well as HDR Brachytherapy planning. Cancer Institute is the first centre in the country to install and upgrade to RapidArc Technology on 22 January 2009.We have FIVE linacs, ONE Telecobalt machine, TWO HDR units and ONE SIMULATOR. Also we have SIX ECLIPSE Treatment Planning systems and ONE MONACO Planning System.

Academic Activities

The Department was the FIRST to start the M.Sc (MEDICAL PHYSICS) course in South ASIA in 1981 in collaboration with ANNA UNIVERSITY. (The PG Degree course is offered at the university).So far over 460 students have passed out and well settled in INDIA and abroad. At present 30 students are enrolled per year.

The Department is also involved in Teaching M.Sc Radiotherapy Technology, BSc RT Technology, B.Sc Radiology Technology and B.Sc Nuclear Medicine Technology.

Research Activities

The Department is involved in research actively and so far ELEVEN Scholars got their  Degrees under the guidance of Dr.N.Vivekanandan. Ongoing studies include, A 3D printed  Insert compatible with QUASAR phantom is successfully fabricated and being tested for  gafchromic film based 4D dosimetry for possible routine clinical use. QA tracker, using python   software is being modelled for cancer institute needs, which will help to track and  analyse Quality Assurance tests of all teletherapy equipment.
