>>>>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may be because such results have never been generated, or because the system considers that the most recent result is no longer valid (perhaps due to age or intervening equipment changes).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)
