10.12.1 Relation With Other Positioning Attributes

The attributes of this macro may be used to correlate the patient based coordinate system (see Section C.7.6.2) and the equipment.

Note

The Patient Orientation Code Sequence (0054,0410) allows a more precise and comprehensive positioning than Patient Position (0018,5100). If this sequence is present Patient Position (0018,5100) is not used.
