Table C.8.31.3-1. Breast X-Ray Detector Macro Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Detector Position Sequence | (0018,9541) | 1 | A sequence that describes the geometrical position of the detector. Only a single Item shall be included in this sequence.
>Detector Primary Angle | (0018,1530) | 1C | Angle of the X-Ray beam in the row direction in degrees relative to the normal to the detector plane. Positive values indicate that the X-Ray beam is tilted toward higher numbered columns. Negative values indicate that the X-Ray beam is tilted toward lower numbered columns. See C.8.11.7.1.2. Required if the detector can be moved in the row direction. May be present otherwise.
>Detector Secondary Angle | (0018,1531) | 1C | Angle of the X-Ray beam in the column direction in degrees relative to the normal to the detector plane. Positive values indicate that the X-Ray beam is tilted toward lower numbered rows. Negative values indicate that the X-Ray beam is tilted toward higher numbered rows. See C.8.11.7.1.2. Required if the detector can be moved in the column direction. May be present otherwise.
