HONEYCOMB RIB STRUCTURE IN ROTATING GANTRY OF PROTON THERAPY DEVICE

摘要

A honeycomb rib structure in a rotating gantry of a proton includes a plurality of upper honeycomb ribs and a plurality of lower honeycomb ribs which are mounted in a cylindrical body through a plurality of connecting structures. The plurality of upper honeycomb ribs and the plurality of lower honeycomb ribs are symmetrically arranged, and are spliced by a plurality of basic structures in a regular hexagonal distribution. Connecting nodes between the adjacent basic structures are of a ring structure. Densities of the plurality of upper honeycomb ribs and the plurality of lower honeycomb ribs are adjusted through a density adjustment structure.
