tereotactic radiosurgery is a three dimensional coordination that locates a target tumor detected in a diagnostic images with its actual location in the body and targeting the tumor for precise radiation surgery rather than excision with a blade. The research result presented here describes development of an optimization technique to replace conventional approach in radiation treatment. Precise radiation treatment is gaining popularity as an alternative to surgery in targeting tumors. The

In conventional method this is achieved through an iterative approach.
