A.83 Ophthalmic Optical Coherence Tomography En Face Image IOD

This Section defines an Information Object to be used with several types of en face images that are derived from volumetric images obtained using optical coherence tomography (OCT) technology. En face images may be based upon structural OCT volumes and segmentation information only, or structural OCT volumes, segmentation information and angiographic flow volume information.

Note

This IOD has been modified with non-backward compatible changes relative to the definition in PS3.3-2024c and prior editions, which was determined to have significant deficiencies for implementation.

A.83.1 Ophthalmic Optical Coherence Tomography En Face Image IOD Description

The Ophthalmic Optical Coherence Tomography En Face Image IOD specifies a Single-frame Image derived from images obtained using OCT technology. This IOD encodes a single derived en face image.
