/**
     * Patient Position (0018,5100) specifies the position of the patient relative to the imaging equipment space.
     * This Attribute is intended for annotation purposes only. It does not provide an exact mathematical
     * relationship of the patient to the imaging equipment.
     * When multiple subjects are present in the same image, and arranged with different positions, then the Patient
     * Position (0018,5100) in the General Series Module is nominal, does not apply to each subject, but does define
     * the relationship of the nominal Patient-Based Coordinate System to the machine.
     * \note In conjunction with the Patient Position (0018,5100) in each Item of the Group of Patients Identification
     * Sequence (0010,0027), Patient Position (0018,5100) in the General Series Module may be helpful to compute
     * patient-relative spatial information for each subject from the Attributes of the Image Plane Module.
     * When facing the front of the imaging equipment, Head First is defined as the patient's head being positioned
     * toward the front of the imaging equipment (i.e., head entering the front of the equipment). Feet First is
     * defined as the patient's feet being positioned toward the front of the imaging equipment (i.e., feet entering
     * the front of the equipment). Left First is defined as the patient's left side being positioned towards the
     * front of the imaging equipment (i.e., patient's left side entering the front of the equipment). Right First
     * is defined as the patient's right being positioned towards the front of the imaging equipment (i.e., patient's
     * right side entering the front of the equipment). Prone is defined as the patient's face being positioned in a
     * downward (gravity) direction. Supine is defined as the patient's face being in an upward direction. Decubitus
     * Right is defined as the patient's right side being in a downward direction. Decubitus Left is defined as the
     * patient's left side being in a downward direction.
     * \note
     * -# For quadrupeds, separate concepts for ventral and dorsal are not introduced, rather it is expected that
     *     anterior and posterior will be considered synonymous as they are when applied to the trunk.
     * -# There are no decubitus variants of left or right first, since for imaging equipment that is aligned
     *     horizontally with respect to gravity the patient cannot be both decubitus and have the left or right
     *     side towards the front of the imaging equipment.
     * -# There are no prone or supine variants of anterior or posterior first, since for imaging equipment that
     *     is aligned horizontally with respect to gravity the patient cannot be prone or supine and have the
     *     anterior or posterior side towards the front of the imaging equipment.
