#### C.8.17.13 Wide Field Ophthalmic Photography Quality Rating Module

Table C.8.17.13-1 specifies the Attributes that evaluate the quality of the projection or mapping used for a wide field ophthalmic photography image.

Table C.8.17.13-1. Wide Field Ophthalmic Photography Quality Rating Module Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Wide Field Ophthalmic Photography Quality Rating Sequence | (0022,1525) | 1 | Type of metric and metric value used to evaluate the quality of the projection or mapping used for the wide field ophthalmic photography image 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 Quality Metric Type” shall be used for Concept Name Code Sequence (0040,A043)
>Wide Field Ophthalmic Photography Quality Threshold Sequence | (0022,1526) | 1 | Quality threshold value and software algorithm used to provide the wide field ophthalmic photography projection or mapping quality rating for this SOP Instance. Only a single Item shall be included in this Sequence.
>>Wide Field Ophthalmic Photography Threshold Quality Rating | (0022,1527) | 1 | Quality rating threshold value for acceptable wide field ophthalmic photography projection or mapping. ### Note The units of this Attribute is the same as defined in Measurement Units Code Sequence (0040,08EA) of the Wide Field Ophthalmic Photography Quality Rating Sequence (0022,1525). The threshold value is not the same as the attribute Numeric Value (0049,A30A) of the Wide Field Ophthalmic Photography Quality Rating Sequence (0022,1525). 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” |
