Body gamma knife is a gamma-ray stereotactic radiation therapy system, it is not a real scalpel, is a stereotactic technology and radiosurgery technology in one, after the head gamma knife to treat body diseases stereotactic radiosurgery equipment.
It adopts gamma ray geometric focusing method, through precise stereotactic orientation, the computer planning of a certain dose of gamma rays from different directions focused on the pre-selected target point in the body, the focusing effect of the point to produce a gamma ray high measurement area, a one-time or several times, lethal destruction of the diseased tissue in the point, in order to achieve the effect of surgical excision or destruction. The normal tissues on the body surface and outside the focus are only transiently irradiated with very small doses and are essentially undamaged.
Body gamma knife can achieve the high dose, high precision, high efficacy and low damage treatment effect that cannot be achieved by ordinary radiotherapy, and can perfectly realize the purpose of precisely focused and conformal radiotherapy. Gamma radiation instead of scalpel, its treatment irradiation range and normal tissue demarcation is very obvious, the edge like a knife cut, people imaginatively called “gamma knife”.
