Abstract

The application provides a gantry assembly, a radiotherapy system and a radiotherapy device, relates to the technical field of medical treatment, and is used for improving a focus dose rate, effectively improving a dose gradient, reducing a treatment process length, improving a radiotherapy effect, and meeting a requirement of a super high dose rate and a clear gradient in clinical treatment. The gantry assembly is applied to the radiotherapy system and comprises a base and a roller. The roller is rotationally arranged on the base. A plurality of first mounting holes which are independent of each other are arranged in a side wall of the roller along an axial direction of the roller. A central axis of the first mounting hole is parallel to a central axis of the roller. The first mounting hole is used for mounting a radioactive source.
