Gantry for a computed tomography apparatus

摘要

A gantry for a computed tomography apparatus has a supporting body and a support ring for a rotatable rotary carriage. The supporting body internally exhibits a channel that communicates in terms of flow with the support ring. A cooling ring with a cooling channel is mounted on the radially-inward circumferential side of the support ring. The cross-section of the cooling channel varies in the circumferential direction. The cooling ring exhibits a cooling ring region that has stiffening ribs.
