|(0018,1110)||Distance Source to Detector||3 ||Distance in mm from source to detector center.|
|(0018,1111)||Distance Source to Patient||3 ||Distance in mm from source to isocenter (center of field of view). |
|(0018,1114)||Estimated Radiographic Magnification Factor||3 ||Ratio of SID (Source Image Distance) over SOD (Source Object Distance).|
|(0018,1450)||Column Angulation||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.
