10.30 Assertion Macro (Current)

## 10.30 Assertion Macro

This Macro is used to record Assertions made by a person or device about the content of a SOP Instance. The nature of the Assertion is defined by the Assertion Code.

The scope of the Assertion (e.g., whether it applies to the whole Instance, to a specific Item in a Sequence, etc.) is described at the point where the Macro is included. It is also expected that when this Macro is included, the Baseline CID for the Assertion Code Sequence (0044,0101) will be constrained.

Table 10.30-1. Assertion Macro Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Assertion Code Sequence | (0044,0101) | 1 | The Assertion being made. Only a single Item shall be included in this Sequence.
>Include Table 8.8-1 “Code Sequence Macro Attributes” | No Baseline CID defined
Assertion UID | (0044,0102) | 1 | Unique identification of this Assertion.
Asserter Identification Sequence | (0044,0103) | 1 | The person or device making the Assertion. Only a single Item shall be included in this Sequence. ### Note Multiple asserters wishing to make the same Assertion may be recorded as multiple Assertions, each with a single asserter.
>Include Table C.17-3b “Identified Person or Device Macro Attributes” | Organizational Role BCID 7452 “Organizational Roles”.
Assertion DateTime | (0044,0104) | 1 | Date and time at which the Assertion was made.
Assertion Expiration DateTime | (0044,0105) | 3 | Date and time at which the Assertion expires. If this Attribute is absent or empty, it means the Assertion does not have a pre-determined date and time at which it expires.
Assertion Comments | (0044,0106) | 3 | Comments on the nature, extent or basis of the Assertion.
Pertinent Documents Sequence | (0038,0100) | 3 | Reference to document(s) that describe the Assertion semantics, or provide the basis for making the Assertion. Items shall not be empty. One or more Items are permitted in this Sequence.
>Referenced SOP Class UID | (0008,1150) | 3 | Unique identifier for the class of the referenced document.
>Referenced SOP Instance UID | (0008,1155) | 3 | Unique identifier for the referenced document as used in DICOM Instance references (see Section C.12.1.1.6)
>HL7 Instance Identifier | (0040,E001) | 3 | Instance Identifier of the referenced document, encoded as a UID (OID or UUID), concatenated with a caret ("^") and Extension value (if Extension is present in Instance Identifier).
>Retrieve URI | (0040,E010) | 3 | Retrieval access path to the referenced document. Includes fully specified scheme, authority, path, and query in accordance with [RFC3986].
Related Assertion Sequence | (0044,0107) | 3 | Other Assertions which may be of interest to systems examining this Assertion. One or more Items are permitted in this Sequence. ### Note For example, an Assertion that overrides a previous Assertion or disapproves a previously approved protocol, could reference the prior approval Instance making it easier to find/correlate/confirm.
>Referenced Assertion UID | (0044,0108) | 1 | Uniquely identifies a related Assertion.
