What is the difference between proton radiation surgery and sharp knife?

Proton radiotherapy generally adopts the irradiation mode of large division and small dose, which has high irradiation accuracy and many treatments. Every treatment interval has a buffer break, and the sharp knife is a single high-dose irradiation, and the treatment process is short. At present, proton radiosurgery has more experience and wide application in the world, but the fast forward knife is still in its infancy. It takes time to test.
