The use of this Context Group in the Patient Orientation Modifier Code Sequence (0054,0412) of the “Nuclear Medicine Image IOD” in PS3.3 and the “Positron Emission Tomography Image IOD” in PS3.3 requires a Coding Scheme Designator value of "99SDM".
In a prior version of this Context Group, the codes G-5190 and G-5191 were specified for the concepts "headfirst" and "feet-first". The use of these codes is deprecated as they are not actually in SNOMED. Although there is minimal possibility of misinterpretation with SOP Instances that may include the deprecated use, receiving applications should be aware of this change; see Annex J.
For devices that do not have a conventional gantry geometry, the vendor of that device may describe in the Conformance Statement how the codes are interpreted with respect to the device geometry.
(126830, DCM, "left first"), (126831, DCM, "right first), (126832, DCM, "posterior first) and (126833, DCM, "anterior first) are more specific than (R-10515, SRT, "transverse") in that they specify which side of the patient is towards the front of the equipment.
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.
