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.
