Today we mainly introduce you to the radio wave knife: 1, radio wave knife is a kind of radiotherapy. 2, compared with the traditional radiotherapy, due to the addition of real-time positioning tracking, more irradiation angle and other technologies, the rays of the radio wave knife can achieve a more accurate irradiation area, more effective protection of the surrounding healthy organs (fewer complications of radiotherapy), and a single implementation of a larger dose of radiotherapy (shortening the overall time of treatment). 3.Radio-wave knife can achieve better therapeutic effect than traditional radiotherapy for many solid tumors, and radiotherapy for prostate cancer is a very good suitable case. 4.Before the radio wave knife treatment, several gold particles should be implanted in the tumor organ to be irradiated, as the mark of the radio wave knife system to locate and track the tumor in the treatment process, for prostate cancer, this process is completed by transrectal puncture.
