xray knife

has anyone suggested xray knife , basically they shoot several low power xray beams from different angles to converge at one single point with a multiplied intensity effect to kill the cancer cells or tumor , i don’t know if they

do the same thing with lasers but might be worth checking on.below are several links to sites explaining technique.

good luck.
