### C.32.3 QA Results Module

This module records the latest results of QA activities, such as calibration, performed on the Display Subsystems.

Table C.32.3-1. QA Results Module Attributes

Attribute Name | Tag | Description
--- | --- | ---
QA Results Sequence | (0028,700F) | Results of QA activities. Exactly one Item shall be included for each Display Subsystem present in the Display System.
>Display Subsystem ID | (0028,7003) | The Display Subsystem ID of the item in the Display Subsystem Sequence (0028,7023) to which these results apply.
>Display Subsystem QA Results Sequence | (0028,7010) | Results of QA activities for the identified Display Subsystem. Zero or more Items shall be included in this Sequence.
>>Configuration ID | (0028,700B) | The Configuration ID of the item in the Display Subsystem Configuration Sequence (0028,700A) under which the QA was performed. A given Configuration ID value shall not appear more than once in this Sequence.
>>Configuration QA Results Sequence | (0028,7011) | Results of QA activities for the identified Display Subsystem in the identified configuration
>>>Display Calibration Result Sequence | (0028,7016) | The most recent calibration result. Zero or one Item shall be included in this Sequence.
>>>>Include Table C.32.3.1-1 “Display QA Result Context Macro Attributes”
>>>>Luminance Characteristics ID | (0028,7009) | The Luminance Characteristics ID of the item in the Target Luminance Characteristics Sequence (0028,7008) that represents the target values used during this calibration.
>>>Visual Evaluation Result Sequence | (0028,7015) | The most recent visual evaluation result. Zero or one Item shall be included in this Sequence.
>>>>Include Table C.32.3.1-1 “Display QA Result Context Macro Attributes”
>>>>Include Table C.32.3.2-1 “Visual Evaluation Result Macro Attributes”
>>>Luminance Uniformity Result Sequence | (0028,7027) | The most recent luminance uniformity result. Zero or one Item shall be included in this Sequence.
>>>>Include Table C.32.3.1-1 “Display QA Result Context Macro Attributes”
>>>>Include Table C.32.3.3-1 “Luminance Uniformity Result Macro Attributes”
>>>Luminance Result Sequence | (0028,7024) | The most recent luminance result. Zero or one Item shall be included in this Sequence.

>>>>Include Table C.32.3.4-1 “Luminance Result Macro Attributes”

### Note

Several Result Sequences in the above table are permitted to contain zero items. This means that no valid "most recent result" exists. This may be because such results have never been generated, or because the system considers that the most recent result is no longer valid (perhaps due to age or intervening equipment changes). Specifying such policy is outside the scope of DICOM.

#### C.32.3.1 Display QA Result Context Macro

This macro records the context for a set of collected display QA results: when they were produced, the person/device that produced them.

Table C.32.3.1-1. Display QA Result Context Macro Attributes

Attribute Name | Tag | Description
--- | --- | ---
Performed Procedure Step Start DateTime | (0040,4050) | Date and Time at which the QA job that generated the results started.
Performed Procedure Step End DateTime | (0040,4051) | Date and Time at which the QA job that generated the results ended.
Actual Human Performer Sequence | (0040,4035) | Human performer(s) responsible for the results. Zero or more Items shall be included in this Sequence.
>Human Performer Code Sequence | (0040,4009) | Coded identification of the human performer. Only a single Item shall be included in this Sequence.
>>Include Table 8.8-1 “Code Sequence Macro Attributes” | No Baseline Context ID is defined.
>Human Performer's Name | (0040,4037) | Name of the human performer.
>Human Performer's Organization | (0040,4036) | Organization to which the human performer is accountable for the results.
Measurement Equipment Sequence | (0028,7012) | Describes the measurement equipment (if any) used in deriving the results. This may describe standalone equipment or may re-iterate details of equipment built into the Display System. Zero or more Items shall be included in this Sequence.
>Measurement Functions | (0028,7013) | Measurement functions of the measurement equipment. Enumerated Values: PHOTOMETER measurement of light intensity COLORIMETER measurement of energy along the visible spectrum ILLUMINOMETER measurement of illumination (ambient luminance) This multi-valued attribute shall contain at most one of each enumerated value. When multiple values are present, the equipment is capable of performing multiple functions.
>Measured Characteristics | (0028,7026) | Characteristic(s) which are measured by the measurement equipment. Enumerated Values: UNIFORMITY Luminance uniformity LUMINANCE Luminance CHROMATICITY Chromaticity ILLUMINANCE Illuminance This multi-valued attribute shall contain at most one of each enumerated value. When multiple values are present, the equipment is capable of measuring multiple characteristics.
>Measurement Equipment Type | (0028,7014) | Type of measurement equipment. See Section C.32.1.2 for Enumerated Values.
>Manufacturer | (0008,0070) | Manufacturer of the measurement equipment.
>Manufacturer's Model Name | (0008,1090) | Manufacturer's model name of the measurement equipment.
>Device Serial Number | (0018,1000) | The measurement equipment serial number.
>DateTime of Last Calibration | (0018,1202) | Date and time of the last calibration of the measurement equipment. ### Note This is likely different than the date of the calibration of the Display System itself.
