Welcome to our department’s journey, which began in November 1957 under the leadership of
Dr. K.S. Chandrasekar, Ph.D. Serving as the Head of the Department, Dr. Chandrasekar laid the foundation for our academic legacy.

In August 1958, we welcomed Dr. A.V. Lakshmanan, Ph.D., who assumed the role of Head of the Department in April 1962. His dedication and leadership shaped the department’s growth until his retirement in August 2006. He retired as Director (Administration), and continued  as an Adviser till 2022.

In April 1965,
Dr. I.S. Balakrishnan, PhD, joined the institute and played a pivotal role until his retirement in April 2007, culminating in the position of Chairman, Physical Sciences.

In July 1993,
Dr. N. Vivekanandan, Ph.D., became a part of our academic family. Since May 2007, he has been serving as the Professor and Head of the Department, leading us with passion and expertise.

Our journey is marked by the dedication and contributions of these visionary leaders, shaping the department into a hub of academic excellence. Join us as we continue to strive for innovation, research, and educational advancement.

Services Offered

Our dedicated team is responsible for developing treatment plans for all cancer patients, employing a range of cutting-edge techniques.

Our routine work covers a spectrum of methodologies, including conventional, conformal, Intensity Modulated Radiation Therapy (IMRT), RapidArc treatment, and Stereotactic Body Radiation Therapy (SBRT) planning. We are also equipped to provide High Dose Rate (HDR) Brachytherapy planning, ensuring a holistic approach to cancer care.

Notably, the Cancer Institute achieved a significant milestone by being the first center in the country to install and upgrade to RapidArc Technology on January 22, 2009. This technological advancement underscores our commitment to staying at the forefront of innovative cancer treatment.

Within our state-of-the-art facilities, we have five linear accelerators (linacs), one Telecobalt machine, two HDR units, and one simulator. To support our planning processes, we have six ECLIPSE Treatment Planning systems and one MONACO Planning System, reflecting our dedication to providing the best possible care through advanced technology.

Academic Activities

In 1981, we proudly pioneered the M. Sc., (Medical Physics) course in South Asia in collaboration with Anna University, establishing a legacy of excellence. This postgraduate degree course is offered at the university and has seen over 460 graduates, who are now making significant contributions in India and internationally.

Our commitment to education continues, with 30 new students enrolling in the M.Sc., (Medical Physics) course each year. As a testament to our comprehensive approach to medical education, we are actively involved in teaching other programs such as M.Sc., Radiotherapy Technology, BSc RT Technology, B.Sc., Radiology Technology, and B.Sc., Nuclear Medicine Technology.

Research Activities

Under the guidance of Dr. N. Vivekanandan, we’ve successfully mentored eleven scholars who have obtained their degrees, contributing to the ever-evolving field of study.

Our current research endeavors showcase our commitment to pushing boundaries. One ongoing study involves the fabrication and testing of a 3D printed insert compatible with the QUASAR phantom. This innovative approach is geared towards gafchromic film-based 4D dosimetry, with the potential for routine clinical application.

In addition, we are actively engaged in the development of a QA tracker using Python software. Specifically tailored to the needs of the Cancer Institute, this tool is designed to model and track Quality Assurance tests for all teletherapy equipment. This initiative aims to streamline and enhance the analysis of crucial quality assurance data, ensuring the highest standards in cancer treatment.
