This paper describes the design of an innovative linear accelerator image-guided radiosurgery(IGRS)device,which is based on a composite twofold rotary gantry structure.The paper discusses five aspects of the innovative device:its overall composition,the safety net space created by the accelerator radiation head as it rotates around the patient's longitudinal axis,the non-coplanar spherical coverage in the direction of the incidence angle for quasi-4π delivery,the structural features of the composite twofold rotary gantry,and the processes of treatment planning and implementation.It elaborates on the device's manufacturing feasibility,safety,effectiveness,accuracy,and efficiency.The conclusion is that this innovative device design holds significant development value and market promotion potential.
