| Ring artifact on computed tomography (finding) | | Ring artifact on CT | | Ring artifact on computed tomography
| | An error caused by a malfunction or miscalibration of a single detector element (or a small group of elements). As the X-ray tube rotates during helical or axial acquisition, the defective detector produces a consistent error at a fixed radial position. During image reconstruction, this error results in concentric circular artifacts. |
