#### C.8.28.3 Ophthalmic Thickness Map Quality Rating Module

Table C.8.28.3-1 specifies the Attributes that describe the quality rating for the ophthalmic mapping.

Table C.8.28.3-1. Ophthalmic Thickness Map Quality Rating Module Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Ophthalmic Thickness Map Quality Rating Sequence | (0022,1470) | 1 | Type of metric and metric value used to evaluate the quality of the ophthalmic mapping for grading and diagnostic purposes for this SOP Instance. Only a single Item shall be included in this sequence.
>Include Table 10-26 “Numeric Value Macro Attributes” | Defined CID 4243 “Ophthalmic Axial Length Quality Metric Type” shall be used for Concept Name Code Sequence (0040,A043)
>Ophthalmic Thickness Map Quality Threshold Sequence | (0022,1458) | 1 | Quality threshold value and software algorithm used to provide the ophthalmic thickness map quality rating for this SOP Instance. Only a single Item shall be included in this sequence.
>>Ophthalmic Thickness Map Threshold Quality Rating | (0022,1460) | 1 | Quality rating threshold value for acceptable ophthalmic map. ### Note The units of this Attribute is the same as defined in Measurement Unit Code Sequence (0040,08EA) of the Ophthalmic Thickness Map Quality Rating Sequence (0022,1470). The threshold value is not the same as the attribute Numeric Value (0049,A30A) of the Ophthalmic Thickness Map Quality Rating Sequence (0022,1470). Therefore, it conveys the least stringent value that is acceptable, not the actual rating for this SOP Instance.
>>Include Table 10-19 “Algorithm Identification Macro Attributes” |
