Abstract: This invention relates to a method for entire removal of a space truss, and an assistive support mechanism therefor. The assistive support mechanism is arranged on a vertical support rod of a truss structure, the assistive support mechanism comprises an assistive support assembly, a lattice support member, and a conversion platform. The lifting assembly is arranged at a top of the conversion platform and comprises a stranded wire, a lifting member, and a control member. The method for entire removal of a space truss comprises mounting the assistive support mechanism, and performing initial removal of the truss structure; lowering the truss structure; and then performing secondary removal of the entire space truss. The major removal work is done on the ground, thereby reducing the requirement for removal-assisting measures and the operational risks, and improving the working efficiency.

Abstract: Patient sitting equipment for radiotherapy, including an installation platform, a treatment couch assembly, a support and adjustment assembly and a 3D imaging assembly. The treatment couch assembly is configured to fix a patient. The support and adjustment assembly is configured to adjust a position of the treatment couch assembly with respect to the installation platform. The 3D imaging assembly includes a column assembly and a 3D imaging device. The column assembly is arranged at the installation platform, and extends along the vertical direction. The 3D imaging device is movably arranged at the column assembly, and is corresponding to the treatment couch assembly in a horizontal projection direction. The 3D imaging device is configured to scan the patient.
