RADIOTHERAPY APPARATUS

摘要

The present invention relates to a multi-joint radiotherapy apparatus using a flexible and rotation connection waveguide. More particularly, the present invention includes a beam irradiation head unit (10); a linear acceleration means (20) that is provided in the beam irradiation head unit (10); a robot arm (30) that is connected to the beam irradiation head unit (10) and is configured to have multiple joints; a waveguide (40) that is built into the robot arm (30) and is connected to the linear acceleration means (20); and an electromagnetic wave generator (50) that is arranged below the robot arm (30) and generates electromagnetic waves so as to spread electromagnetic wave to the linear acceleration means (20) through the waveguide (40). According to the present invention, the electromagnetic wave generator is separated from the beam irradiation head unit to reduce the weight of the beam irradiation head unit and a load that is applied to the multi-joint robot arm for supporting the beam irradiation head unit is reduced so that precise operation control is available.
