C.8.7.6 XRF Positioner Module

Table C.8-31XRF POSITIONER MODULE ATTRIBUTES

Attribute Name Tag Type Attribute Description
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 isocenter (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.
