3-D treatment planning system-Leksell Gamma Knife treatment planning system

Leksell Gamma Plan (LGP), the treatment planning system for the Leksell Gamma Knife (LGK) stereotactic radiosurgery, has evolved from the primitive KULA system to the present-day powerful version of image-guided stereotactic radiosurgery. Through many years of development, LGP has improved on its dose calculation accuracy, speed, and user interface. This allows more accurate irradiation of the target while sparing the nearby normal tissues and critical structures better.
