A.67.1 Ophthalmic Thickness Map IOD Description

The Ophthalmic Thickness Map IOD is generated by ophthalmic thickness mapping devices, such as retinal nerve fiber layer analyzers and optic nerve head analyzers, to generate measurements that are presented topographically using a monochromatic image and a pseudo-color map.

A.67.2 Ophthalmic Thickness Map IOD Entity-Relationship Model

The E-R Model in Section A.1.2 depicts those components of the DICOM Information Model that are referenced by the Ophthalmic Thickness Map IOD. Below the Series IE, only the Image IE is used.
