Distance Source to Detector
|
(0018,1110)
|
3
|
Distance in mm from source to detector center.
Note
This value is traditionally referred to as Source Image Receptor Distance (SID).

|
Distance Source to Patient
|
(0018,1111)
|
3
|
Distance in mm from source to center of field of view.
Note
This value is traditionally referred to as Source Object Distance (SOD).
|
|
Estimated Radiographic Magnification Factor
|
(0018,1114)
|
3
|
Ratio of SID (Source Image Receptor Distance) over SOD (Source Object Distance).
|
|
Column Angulation
|
(0018,1450)
|
3
|
Angle of the X-Ray beam in degree relative to an orthogonal axis to the detector plane. Positive values indicate that the tilt is towards the head of the table.
Note
The detector plane is assumed to be parallel to the table plane.
