Furthermore, the outer sides of the roller supporting base and the rotary focusing device are provided with device shells.
In order to achieve the above object, the present invention provides a stereotactic radiotherapy method comprising the steps of:
step S1: fixing a person to be treated in the stereotactic radiotherapy device;
