|
Other failure |
Failure that is not mechanical or electrical or otherwise described. |
|
111210
|
Motion blur |
Unacceptable image blur resulting from motion of the anatomy of interest during exposure or the inadequately compensated motion of X-Ray source with respect to the image detector during exposure. |
|
111221
|
Unknown failure |
Unidentified or unknown cause of failure. |
|
111211
|
Under exposed |
Inadequate number of quanta reached the detector during exposure. Reasons for under exposed images include low kVp, low mAs product, excess Source Image Distance. Under exposed images have inadequate signal and higher noise in the areas of interest. |
|
111209
|
Positioning |
Inadequate arrangement of the anatomy of interest with respect to the X-Ray field and image detector sensitive area. Examples: 1) positioning is "cutoff" when the projection of anatomy of interest falls outside the sensitive area of the detector; 2) "cone cut", in which the X-Ray field does not adequately cover the anatomy of interest; 3) detector's sensitive surface is too small to cover the projection of the anatomy of interest; 4) improper angular orientation or "rotation" of anatomy of interest with respect to the X-Ray source, or detector; 5) projection of other anatomy or clothing over the anatomy of interest in the image. |

|
Over exposed |
An excess number of quanta reached the detector during exposure. Reasons for over exposed images include high kVp, high mAs product, short Source Image Distance. Over exposed images have high signal and lower noise in the areas of interest. Over exposed area may demonstrate lack of contrast from over saturation of the detector. |

|
No image |
No evidence of a patient exposure. |
|
111214
|
Detector artifact(s) |
Superposed features or flaws of the detector. |
|
111215
|
Artifact(s) other than grid or detector artifact |
Features or discontinuities arising from causes other than the anti-scatter grid and image detector. |
|
111216
|
Mechanical failure |
Failure of the device to operate according to mechanical design specifications. |
|
111217
|
Electrical failure |
Failure of a device to operate according to electrical design specifications. |
|
111218
|
Software failure |
Attributable to software used in generation or handling of image. |
|
111208
|
Grid artifact(s) |
Feature(s) arising from the acquisition unit's anti-scatter grid mechanism. For two-dimensional systems, such features include those of mechanically damaged or incorrectly positioned grids. For moving or Bucky grids, artifacts may result from intentional grid motion that is inadequate in duration or velocity uniformity. |

Inappropriate image processing |
Images processed inappropriately, not following appropriate protocol. |
