Abstract
Among other things, a computed tomography (CT) imaging modality is provided. The imaging modality includes a radiation source that emits radiation. The imaging modality includes a detector array that detects at least a portion of the radiation. The imaging modality includes a rotating structure that rotates about an axis. The rotating structure includes a first support portion having a first shape. The rotating structure includes a second support portion having a second shape different than the first shape. The radiation source and the detector array are mounted to the second support portion.

A computed tomography (CT) imaging modality, comprising:
- a radiation source configured to emit radiation;
- a detector array configured to detect at least a portion of the radiation;
- and
- a rotating structure configured to rotate about an axis, the rotating structure comprising:
- a first support portion defining a substantially cylindrical interior cavity;
- and
- a second support portion defining a non-cylindrical interior cavity, wherein the radiation source and the detector array are mounted to the second support portion, and
- wherein the first support portion is disposed within the non-cylindrical interior cavity of the second support portion.
A computed tomography (CT) imaging modality, comprising:
- a radiation source configured to emit radiation;
- a detector array configured to detect at least a portion of the radiation;
- and
- a rotating structure configured to rotate about an axis, the rotating structure comprising:
- a first support portion comprising a wall defining a substantially cylindrical interior cavity, wherein the wall of the first support portion has an outer radial surface, diametrically opposing the substantially cylindrical interior cavity, that has a circumference;
- and
- a second support portion comprising a wall defining a non-cylindrical interior cavity, wherein:
- the wall of the second support portion comprises a first wall segment having an inner surface that in part defines the non-cylindrical interior cavity, the inner surface of the first wall segment lying in a first plane;
- the wall of the second support portion comprises a second wall segment having an inner surface that in part defines the non-cylindrical interior cavity, the inner surface of the second wall segment lying in a second plane;
- and
- the first support portion is disposed within the non-cylindrical interior cavity of the second support portion.
