First of all, the gamma knife is an international generic name, other languages are the same expression, and the "X knife" is the basic for the promotion of domestic linear accelerator and the creation of the name. Strictly speaking, "X knife" difficult to achieve like gamma knife so keen similar to the effect of the operation.
Secondly, on the head of disease, the gamma knife is by nuclear magnetic resonance and positioning, "X knife" to use CT positioning, which caused the "X knife" is unable to distinguish small lesions and fine structures in the skull base will be greatly disturbed. Therefore, it is not suitable for the treatment of small tumors, multiple tumors and trigeminal neuralgia.
Because the gamma knife is fixed, the mechanical part of relative displacement is very small, so the mechanical precision is very high, especially after a period of time, the wear and deformation effect. Relative to the "X knife" because of the mechanical arm, the treatment bed, moving in three dimensions, the accuracy will be affected, so it is more suitable for the treatment of other parts of the body, larger lesions.
However, the gamma knife has its inherent defects, mainly to the radiation source, and the existence of decay, every time to replace the cobalt source, so the cost is high, but because of China's policy requirements, the gamma knife treatment fee is very low, most of the patients can endure. "X knife" is no ray in the treatment, and the gamma knife is a continuous radiation release, although there is a door, but in the medical personnel or gamma knife will be more exposed to radiation, we center personnel in after a few years of work in the physical examination often have abnormal blood routine, so in treatment family should be removed before and after gamma knife. Therefore, now the number of gamma knife equipment is far less than the "X knife".
The gamma knife has the same equipment incomparable advantages in the treatment of head disease, but as a means of treatment, if used improperly, may also damage, understand the difference, gamma knife and X knife ", must be careful selection of indications, standard treatment. Tel: 010-81240570 (2)
