10.12 Patient Orientation MACRO

This section describes attributes of the Patient Orientation Macro by specifying the patient orientation related to gravity and equipment. Table 10-15 contains IOD Attributes that describe the Patient Orientation related to gravity and equipment.

Table 10-15 PATIENT ORIENTATION MACRO ATTRIBUTES

Attribute Name Tag Type Attribute Description
Patient Orientation Code Sequence (0054,0410) 1 Sequence that describes the orientation of the patient with respect to gravity. See C.8.11.5.1.2 for further explanation. Only a single Item shall be included in this Sequence.
>Include ‘Code Sequence Macro’ Table 8.8-1. Baseline Context ID 19
>Patient Orientation Modifier Code Sequence (0054,0412) 1C Patient orientation modifier. Required if needed to fully specify the orientation of the patient with respect to gravity. Only a single Item shall be included in this Sequence.
>>Include ‘Code Sequence Macro’ Table 8.8-1. Baseline Context ID 20
Patient Gantry Relationship Code Sequence (0054,0414) 3 Sequence that describes the orientation of the patient with respect to the head of the table. See Section C.8.4.6.1.3 for further explanation. Only a single Item is permitted in this Sequence.

10.12.1 Relation with other positioning attributes

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

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