The OPT Image, Ophthalmic Tomography Angiographic Adjunctive Image and the Ophthalmic Tomography Angiographic En Face Image SOP Instances all reside in different DICOM series. They share the same spatial Frame of Reference which is identified in Attribute Frame of Reference UID (0020,0052). Figure C.8.xx-2 illustrates the relationships between the OCT-A based SOP Instances. Figure C.8.xx-2: Relationships Between OCT-A Based SOP Instances C.8.xx.2.1.2 OPT Surface Segmentation Labels The OPT Image SOP Instance uses the Attribute Segment Label (0062,0005) of the Surface Segmentation Module to delineate anatomical boundaries (layers) captured in the OPT Image SOP Instance. Ophthalmic Tomography Surface Segmentation Label(s) (00gg,ee12) identifies one or more segmentation (layers) used to generate the derived en face image. The values conveyed in Ophthalmic Tomography Surface Segmentation Labels (00gg,ee12) are taken from Segment Label (0062,0005) within the referenced OPT Image SOP Instance. C.8.xx.2.1.3 Ophthalmic Image Type Code Sequence Implementations may generate many different types of derived en face images. Figure C.8.xx-3 illustrates various derived enface image types. The Ophthalmic Image Type Code Sequence (00gg,ee15) is used to identify the type of derived en face image.
