  • Special Achievements

 Technology development:
 Development of 3-dimensional radiotherapy treatment planning system

The Department has successfully designed the first 3 dimensional indigenous radiation treatment planning system under a project from the Department of Electronics, Government of India in collaboration with the Centre for Development of Advanced Computing (C-DAC), Pune  and M/s TSG Integrations, New Delhi. This treatment planning system costing around Rs. 42 lakhs is presently being marketed by M/s TSG Integrations and is comparable to similar systems available world wide.
SGPGI was mainly responsible for providing the basic requirements of this 3D-TPS, conceive the different functions and applications that would be needed to make this a state-of-art 3D-TPS and carry out patient/field trials.

Present status and expansion areas

The Department is undergoing a major expansion process. Mecaserto simulator CT, Isis advanced 3D treatment planning system and lab facilities for tumor biology studies have been recently established through Indo-French assistant protocol. The department has added Clinac 600 C, a Low Energy Linear Accelerator in 2005 funded through the Ministry of Health & Family Welfare, Government of India.

The Department had also added a Clinac 2100CD, a High Energy Linear Accelerator with MLC and mMLC for establishing the state the art of radiation therapy like Stereotactic radiotherapy (SRS/SRT), Conformal radiotherapy (3DCRT) and Intensity modulated radiation therapy (IMRT), Varis network system, Eclipse and Helios treatment planning system, Multi slice CT scanner with virtual simulation and tele-radiotherapy system through a grant received from Department of Science and Technology, New Delhi, Government of India.

Further, the Ministry of Health & Family Welfare, Government of India has recognized as Regional Cancer Centre has sanctioned a grant for augmenting a MLC and Portal Imaging in the Clinac 600C, Image guided radiation therapy (IGRT) facility in Clinac 2100CD and ancillary equipment accessories.

The high dose rate brachytherapy which is being practiced over the last 10years inthe department is also planned to add ultrasound and inaged based brachytherapy to complete range of brachytherapy facilities.
