Table C.8.21.3.1.3-1X-RAY 3D GENERAL POSITIONER MOVEMENT MACRO

Attribute Name Tag Type Attribute Description
Primary Positioner Scan Arc (0018,9508) 1C Total amount of rotation of the primary positioner in degrees. Required if present and consistent in the contributing SOP Instances. Required if Modality (0008,0060) is MG.
Primary Positioner Scan Start Angle (0018,9510) 1C Start position of the primary positioner in degrees. See C.8.7.5.1.2 or C.8.11.7, depending on modality and positioner type. Required if present and consistent in the contributing SOP Instances. Required if Modality (0008,0060) is MG.
Primary Positioner Increment (0018,9514) 1C Nominal increment of the primary positioner angle in degrees. Positive values indicate moving from RAO to LAO position through the anterior, or right to vertical. See C.8.7.5.1.2 or C.8.11.7, depending on modality and positioner type. Required if present and consistent in the contributing SOP Instances. Required if Modality (0008,0060) is MG.
Secondary Positioner Scan Arc (0018,9509) 1C Total amount of rotation of the secondary positioner in degrees. Required if present and consistent in the contributing SOP Instances.
Secondary Positioner Scan Start Angle (0018,9511) 1C Start position of the secondary positioner in degrees. See C.8.7.5.1.2 or C.8.11.7, depending on modality and positioner type. Required if present and consistent in the contributing SOP Instances.
Secondary Positioner Increment (0018,9515) 1C Nominal increment of the secondary positioner angle in degrees. Positive values indicate moving from CAU to CRA through the anterior, or from anterior to posterior. See C.8.7.5.1.2 or C.8.11.7, depending on modality and positioner type. Required if present and consistent in the contributing SOP Instances.
