Abstract
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.
Claims18
A gantry for a computed tomography apparatus, comprising:
- a supporting body;
- a support ring mounted in said supporting body, said support ring supporting a rotary carriage that is rotatable in said support ring in a rotation direction, and said support ring comprising a cooling channel for supply of a coolant to the rotary carriage, said cooling channel continuously proceeding around said support ring in a circumferential direction corresponding to said rotation direction;
- and
- said cooling channel having a cross-section that varies along said circumferential direction.
A computed tomography apparatus comprising:
- a rotary carriage carrying x-ray imaging equipment;
- and
- a gantry comprising a supporting body, a support ring mounted in said supporting body, said support ring supporting said rotary carriage for rotation of the rotary carriage in a rotation direction, and said support ring comprising a cooling channel for supply of a coolant to the rotary carriage, said cooling channel proceeding continuously around said support ring in a circumferential direction corresponding to said rotation direction, and said cooling channel having a cross-section that varies along said circumferential direction.
