Relative X-Ray Exposure Attribute

Tag(0018,1405)
TypeOptional (3)
KeywordRelativeXRayExposure
Value Multiplicity1
Value RepresentationInteger String (IS)

Indication of the applied dose, in manufacturer specific units.

Note

  1. This value is intended to provide a single location where manufacturer specific information can be found for annotation on a display or film, that has meaning to a knowledgeable observer.

  2. This may be a calculated or measured value. Examples are the detector entrance dose (KB), the CR sensitivity value (S), or the logarithmic median (lgM).

  3. DICOM specifies standard Attributes in Table 10-23 'Exposure Index Macro', which are recommended.

Attribute Description

Exposure Index

(0018,1411)

3

Measure of the detector response to radiation in the relevant image region of an image acquired with a digital X-Ray imaging system as defined in IEC 62494-1.

Note

  1. A string rather than binary Value Representation is used for this Attribute, in order to allow the sender to control the precision of the value as suggested in the report of AAPM Task Group 116.

  2. This index value is scaled as defined by IEC 62494-1.

Target Exposure Index

(0018,1412)

3

The target value used to calculate Deviation Index (0018,1413) as defined in IEC 62494-1.

Deviation Index

(0018,1413)

3

A scaled representation of the difference of the Exposure Index compared to the Target Exposure Index as defined in IEC 62494-1 and the report of AAPM TG 116.
