Radio-wave knife is more advanced than Gamma Knife. Radio-wave knife is equivalent to the upgraded version of Gamma Knife in the following aspects. 1. Ray optimization: Gamma Knife uses 201 fixed rays, and there are only four choices of ray diameter: 4mm, 8mm, 14mm and 18mm; Radio Wave Knife uses a computer to choose the most practical rays among thousands of rays, and there are 12 choices of ray diameter from 5 to 60mm. 2. Head frame fixation: Gamma Knife needs to be fixed with a head frame, while Radio Wave Knife does not need a head frame, which eliminates the time and pain of installing and dismantling the head frame. 3. Indications: Gamma Knife is mainly applied to tumors <3cm in the head, while Radio Wave Knife can treat tumors of the whole body and can treat lesions up to 15cm in size. 4. Tumor localization: Gamma Knife cannot detect whether the target area is moving during treatment; Radio Wave Knife will frequently use X-ray to locate the target area during irradiation, and it can automatically judge and correct the direction of irradiation, and it can even correct the movement of the target area caused by respiration. Although radio wave knife is more advanced than gamma knife, but the price is higher, and at present the technology is also less in the country. It is recommended that patients consult a specialist to choose the appropriate treatment according to their condition and personal wishes.
