##### A.84.3.2.1 Ophthalmic Optical Coherence Tomography B-scan Volume Analysis IOD Content Constraints

This source for an Ophthalmic Optical Coherence Tomography B-scan Volume Analysis SOP Instance is one or more multi-frame Ophthalmic Tomography SOP Instance(s). The correlation is encoded at the Frame Level and conveyed in the Derivation Image Macro (see Section C.8.17.14.1.7 for examples).

###### A.84.3.2.1.1 Derivation Image Functional Group

The following constraints to the Derivation Image Macro shall apply:

1. Derivation Image Sequence (0008,9124) shall be Type 1

2. The value for Derivation Code Sequence (0008,9215) shall be (128303, DCM, "OCT B-scan analysis")

3. Source Image Sequence (0008,2112) shall be Type 1 and contain one Item. The referenced SOP Instance shall have the same value for Frame of Reference UID (0020,0052) as this SOP Instance

4. The value for Referenced SOP Class UID (0008,1150) shall be Ophthalmic Tomography Image Storage ("1.2.840.10008.5.1.4.1.1.77.1.5.4")

5. The value for Purpose of Reference Code Sequence (0040,A170) shall be (128250, DCM, "Structural image for imaging processing")

6. The value for Spatial Locations Preserved (0028,135A) shall be YES
