Required if the Patient is an animal and the anatomical Frame of​

Reference is not bipedal. May be present otherwise. See​

Section C.7.6.1.1.1 and Section C.7.6.2.1.1.​

Note​

If this Attribute is not present, the default human standard​ anatomical position is used to define the patient orientation​ of projection images and the Patient-Based Coordinate​ System of cross-sectional images.​
