UUU.2 Relationship Between Ophthalmic Tomography Image and Ophthalmic Optical Coherence Tomography B-scan Volume Analysis IODs
Prev	UUU Ophthalmology Use Cases (Informative)	Next

This Section provides examples of the relationship between the Ophthalmic Tomography Image SOP Instance(s) and Ophthalmic Optical Coherence Tomography B-scan Volume Analysis SOP Instance(s).

Below is a typical example.

Ophthalmic Tomography Image SOP Instance UID is "1.2.3.4.5" and contains five frames.
Ophthalmic Optical Coherence Tomography B-scan Volume Analysis SOP Instance encodes five frames (e.g., one frame for each ophthalmic tomography frame).
References are encoded via the Per-frame Functional Groups Sequence (5200,9230) using Attributes Derivation Image Sequence (0008,9124) and Source Image Sequence (0008,2112).

Below is a more complex example.

Ophthalmic TomographyImage SOP Instance UID is "2.3.4.5" and contains 3 frames.
Ophthalmic TomographyImage SOP Instance UID is "1.6.7.8.9" and contains 2 frames.
Ophthalmic Optical Coherence Tomography B-scan Volume Analysis SOP Instance encodes five frames (e.g., one frame for each Ophthalmic TomographyFrame from the two Ophthalmic Tomography Image SOP Instances).
