Abstract
A CT system includes a gantry having a rotatable base and having an opening for receiving an object to be scanned, and a detector assembly. The detector assembly includes a plurality of detectors positioned to receive x-rays having passed through the object, and an arcuate structure positioned to support the plurality of detectors. A first support frame is attached to the rotatable base at a first axial location and supported at a second axial location, wherein the arcuate structure is attached to the first support frame between the first axial location and the second axial location.

A CT system comprising:
- a gantry having a rotatable base and having an opening for receiving an object to be scanned;
- a detector assembly comprising:
- a plurality of detectors positioned to receive x-rays having passed through the object;
- and
- an arcuate structure positioned to support the plurality of detectors;
- and
- a first support frame attached to the rotatable base at a first axial location and supported at a second axial location, wherein the arcuate structure is attached to the first support frame between the first axial location and the second axial location.
A method of assembling a CT system, comprising:
- coupling a rotatable base to a gantry, the gantry having an opening for receiving an object to be scanned;
- attaching an arc-shaped structure to the rotatable base via a first support frame such that the arc-shaped structure is supported at a first axial location and a second axial location;
- and
- positioning a plurality of detectors on a surface of the arc-shaped structure to receive x-rays that pass through the opening and through the object.
A detector assembly for a CT imaging system, the assembly comprising:
- an arced structure having a plurality of detectors positioned thereon, wherein the assembly is attachable to a rotatable base of the CT system such that x-rays generated in the imaging system impinge upon the plurality of detectors after having passed through an object to be imaged;
- and
- a first support frame that axially straddles the arced structure and supports the arced surface at a first axial location and a second axial location.
