## A.5 HL7 CDA Release 2 Diagnostic Imaging Report Target Structure

The HL7 development framework (HDF) uses a model driven methodology and the derivation of specifications and interim work products from a common set of reference models (HL7 V3 Guide). The basis for Refined Message Information Models is the HL7 Reference Information Model (RIM). The CDA RMIM contains act classes, entities, roles and participations derived from the core RIM artifacts. The structured part of the CDA RMIM (Clinical Statement) specifies generic act entry classes such as act and observation. The code attribute of the entry classes is used to convey the semantic information while generic class names are used for the different act entries. Similarly the type code of the entry relationships denotes the semantics of the relationship between act entries.

The HL7 CDA XML representation builds on the HL7 V3 XML Implementation Technology Specification - Data Types and XML Implementable Technology Specification for V3 Structures. XML structures are derived from Hierarchical Message Descriptions (HMD).

The header of the transcoded diagnostic imaging report contains the participations and act relationships that are related to the central ClinicalDocument act class. The clinical document contains the structured body of the CDA document that consists of one or multiple sections. Each document section contains an optional section code and narrative text. Sections are associated with optional entry act classes and their related participations. Entry act classes are connected by act relationships that denote the type of relationship between individual act entries.

DICOM UIDs are mapped to HL7 V3 Instance Identifier (II) data type root. Non UID DICOM identifiers and numbers are mapped to the HL7 V3 Instance Identifier (II) data type extension portion. In this case the root value of the assigning authority (custodian organization) shall be used.

### A.5.1 Constrained HL7 CDA Release 2 Diagnostic Imaging Report RMIM

The constrained CDA RMIM for Diagnostic Imaging Reports transcoded from DICOM SR Basic Diagnostic Imaging Reports shows the relevant artifacts of the target CDA document (refer to CDA Diagnostic Imaging Report RMIM).

#### A.5.1.1 Header (Level 1)

General Remarks on the mapping of DICOM header module attributes:

SR Document General Module

- Custodian:The Type 3 DICOM Custodial Organization Sequence ((0040,A07C) attribute values of the original SR document are not necessarily the basis for mapping to the CDA Custodian Participation, related roles and entities, since the custodian values of the transformed CDA document shall be set according to institution policies.

- Mapping of the Participant Sequence (0040,A07A): Participations of type "SOURCE" (Equipment that contributed to the content) are not mapped to CDA Release 2. The DICOM TID 2000 (PS3.16) does not specify default values for the device observer that are based on the participant sequence.

- Attributes of the Predecessor Documents Sequence (0040,A360) and Identical Documents Sequence (0040,A525) are not mapped since they are relevant only in the context of the original DICOM SR document.

- Attributes of the Current Requested Procedure Evidence Sequence (0040,A375), Pertinent Other Evidence Sequence (0040,A385) and Equivalent Document Sequence (0040,A090) are not mapped since they are relevant only in the context of the original DICOM SR document.

SOP Common Module

- Timezone Offset From UTC (0008,0201) shall be considered for attributes of the original DICOM SR document that are based on the DA or TM data type (PS3.5).

- The Specific Character Set (0008,0005) is required (Type 1C), if the Basic Graphic Set is expanded or replaced. This is the basis for mapping DICOM character sets to CDA Unicode (<?xml version="1.0" encoding="UTF-8"?>)

  ### Note

  Ambiguities exist for mapping individual characters to Unicode (e.g., for Japanese characters). Resolution of those issues is beyond the scope of this document. Please refer to Section A.8 for further details on data types and character sets.

Legal Authenticator Participation

The SR Document General Module attributes related to document verification (PS3.3) are mapped to the legal authenticator participation, associated role and entities as specified in Table A.5.1.1-5, Table A.5.1.1-6, Table A.5.1.1-7 and Table A.5.1.1-8.

SR Document General Module, Verifying Observer Sequence (0040,A073): The constrained DICOM SR Basic Diagnostic Imaging Report is restricted to cover exactly one Verifying Observer since CDA R2 only allows for a single Legal Authenticator. The Verification Flag (0040,A493) cannot be mapped since CDA Release 2 does not specify such flags. If however legalAuthenticator attribute values are set, that implies that the document is verified. If not, the document is unverified. Recommendation: Each transformed DICOM SR document that is sent to information systems should be verified after it has been transcoded. Only verified documents should be exported.

Information Recipient Participation

The referring physician is considered the primary information recipient for both, inpatient as well as outpatient delivery of imaging services by default.

Information on the attending physician may be encoded by using the encompassing encounter | encounter participation (refer to Table A.5.1.1-25, Table A.5.1.1-26 and Table A.5.1.1-27). This participation may also be used for encoding information of the referrer if the primary information recipient is different from the referring physician.

CDA Section Text

Section.text contains the narrative text (attested content) of the document. Section.text is populated from DICOM SR content items of the original document in a way that the full meaning can be conveyed in an unambiguous manner by applications that render the document.

Structured CDA entries may be referenced within the narrative section text of the CDA document (refer to the CDA Release 2 Standard, Section 4.3.5.1 on <content>). Parts of the structured body of the CDA document that are part of the attested content of the document shall be included in the narrative section text. To that end corresponding CDA entries are extended by originalText elements and reference values that can be derived from the entry act class code displayName.

Section.title and Section.text values shall be populated as shown in Table A.5.1.2-1 above if the section is intended to be rendered. Sections that are not intended to be rendered such as the DICOM Objects Catalog shall not contain title and/or text values.

Structured Body and Sections

Figure A.5.1.2-1. Nested Sections

DICOM SR Basic Diagnostic Imaging Reports include nested container content items. The root content item (value type "CONTAINER") includes document sections (content items of value type "CONTAINER") by applying relationships between those content items (relationship type "CONTAINS").

The ClinicalDocument act class is associated with the StructuredBody act class by an act relationship (typeCode "COMP"). The structured body of the CDA contains sections that may be nested (recursive act relationship, typeCode = "COMP"). Nested DICOM SR sections within the document body are not used for SR Basic Diagnostic Imaging Reports (TID 2000). For other SR document types nested sections are mapped as shown in Figure A.5.1.2-1.

DICOM Object Catalog Section

The DICOM Object Catalog Section provides a single location for the identifying information of the study/series/instance hierarchical context of DICOM composite objects that are referenced for a specific purpose (Refer to Section A.7.1 A_DicomSequence minimal (COCT_RM830110UV) for details. In the context of the CDA, entry act class and actRelationships names shall be used as specified for the CDA mapping).

#### A.5.1.3 Structured Body (Level 3)

Coded Observations

DICOM TID 2000 specifies that Imaging Report Elements of Value Type Code are contained in sections (row 6 and 8). The Imaging Report Elements are inferred from Basic Diagnostic Imaging Report Observations (Row 9) that consist of image references and measurements (linear, area, volume and numeric). Coded DICOM Imaging Report Elements in this context are mapped to CDA coded observations that are section components and are related to the SopInstance or QuantityMeasurement act classes by the SPRT (Support) act relationship (Figure A.5.1.3-1).

Figure A.5.1.3-1. Coded Observation Within Section

Table A.5.1.3-1 shows the mapping of attribute values for DICOM Imaging Report Elements to CDA coded observation. The component act relationship between Section and CodedObservation is encoded as a section entry in CDA; CodedObservation as an observation CDA entry and the support act relationship as entryRelationship.

Text Observations

DICOM TID 2000 specifies that Imaging Report Elements of Value Type Text are contained in sections (Rows 6 and 10). The Imaging Report Elements are inferred from Basic Diagnostic Imaging Report Observations (Row 11) that consist of image references and measurements (linear, area, volume and numeric). Coded DICOM Imaging Report Elements in this context are mapped to CDA text observations that are section components and are related to the SopInstance or QuantityMeasurement act classes by the SPRT (Support) act relationship (Figure A.5.1.3-2).

Figure A.5.1.3-2. Text Observation Within Section

Table A.5.1.3-2 shows the mapping of attribute values for DICOM Imaging Report Elements to CDA text observation. The component act relationship between Section and TextObservation is encoded as a section entry in CDA; TextObservation as an observation CDA entry and the support act relationship as entryRelationship.

Image References and Measurements within Section

Image references and measurements (linear, area, volume and numeric) may also be inserted directly within sections (TID 2000, Rows 6 and 12). In this case CDA sections are related to SopInstance and/or QuantityMeasurement act classes via component (COMP) act relationships.

Quantity Measurement + DICOM Composite Object References

For the modeling of DICOM Composite Object References refer to Section A.7.2 Updated Pattern Based on A_DicomCompositeObjectReference Minimal (COCT_RM830120UV). In the context of the CDA, entry act class and actRelationships names shall be used as specified for the CDA mapping.

The mapping of observations (i.e., quantity measurements based on image data) is specified below (structured contents of linear, area, volume and numeric measurements). The updated pattern based on CMET COCT_RM830120 "ReferencedDicomComposite Object" (refer to Section A.7.2) is reused for the mapping. Instead of starting directly with the SopInstance Act Class, the COCT_RM830120 pattern is applied in the context of Quantity Measurements (refer to Figure A.5.1.3-3 for details).

Subject Act Relationship (QuantityMeasurement to SopInstance)

Equivalent DICOM relationship types of the CDA SUBJ actRelationship in this context are: INFERRED FROM and R-INFERRED. CDA Release 2 does not specify reference relationships. However act class clones that carry a unique identifier only and omit other attribute values of the original act class may be used to that purpose.

The relation of quantity measurements to procedures and acts is specified in Section A.5.1.4.2 Procedure Context.

Figure A.5.1.3-3. Quantity Measurement and DICOM Composite Object Reference

The act relationships shown in Figure A.5.1.3-3 are encoded as entryRelationships in CDA; the act classes are represented as observations.

DICOM SR numeric measurements (value type NUM) are mapped to the QuantityMeasurement act class.

The QuantityMeasurement act class is associated with one or more SopInstance act classes. SopInstance is associated with zero or one PurposeOfReference act class through the reason entry relationship.

Multi-frame Image References

The DICOM Image Reference Macro (used for SR content items of value type IMAGE) allows for referencing individual frames of a multi-frame image if the reference does not apply to all frames. The individual referenced frames (DICOM attribute "Referenced Frame Number" (0008,1160)) are mapped to the value attribute (list of integers) of the boundary act class. For mapping quantity measurements (applies to SR template 1400, 1401, 1402 and 1404) that are related to frames of a multi-frame image, one ReferencedFrames act class is associated with SopInstance through an entryRelationship of type code component (Figure A.5.1.3-3). The DICOM code 121190 "ReferencedFrames" is assigned to the ReferencedFrames.code attribute. The ReferencedFrames act class is related to one Boundary act class through an entryRelationship of type code component. In the context of mapping DICOM TID 2000 the Boundary.value attribute contains the referenced frame number of the frame that is the basis for measurements or coded purpose of reference terms.

#### A.5.1.4 DICOM SR Observation Context

The observation context comprises the observer context data (the human observer or device that made the observation), the procedure context data (related to data acquisition and interpretation) and the subject context data (for patient, specimen and fetus being subject to the reported procedure). Section A.5.1.4.1, Section A.5.1.4.2 and Section A.5.1.4.3 specify the mapping.

##### A.5.1.4.1 Subject Context

Subject Context, Patient

Figure A.5.1.3-4. Patient Context

DICOM TID 2000 constrains the multiplicity of the patient subject to one per document. Attributes of the Patient Module (PS3.3) and the Patient Subject Context (TID 1007) are mapped to the recordTarget participation, associated roles and entities, if the Subject Class Code (TID 1006) equals "Patient".

Table A.5.1.3-7. Patient Role

Attribute | Data Type | Multiplicity | Value
--- | --- | --- | ---

### Note

If information on Issuer of Patient ID is available from the DICOM SR document (Patient Module), Universal Entity ID (0040,0032) of the Issuer of Patient ID Qualifiers Sequence (0010,0024) are mapped to PatientRole.id II root and Patient ID (0010,0020) to PatientRole.id II extension. Otherwise a globally unique identifier (ISO Object Identifier) may be generated for the PatientRole.id II root portion. If available Issuer of Patient ID (0010,0021) shall be mapped to PatientRole.id assigningAuthorityName.

CDA Release 2 does not specify a subject ID for mapping of Fetus Subject UID. Also the DICOM SR NUM content item that conveys the number of fetuses cannot be mapped because CDA Release 2 does not specify such an attribute. The fetus subject is always mapped in combination with the mother record target artifacts.

CDA Entries (Clinical Statement, Structured Body)

If individual sections are used to report on one or multiple procedures, the procedure code values of the Procedure Context (TID 1005) associated with the DICOM section container content item are mapped to the CDA clinical statement entry class attribute Act.code or Procedure.code. The selection of the "Procedure" or "Act" entry from the clinical statement choice box depends on the nature of the imaging service that has been performed. The "Procedure" entry shall be used for image-guided interventions and minimal invasive imaging services, whereas the "Act" entry shall be used for diagnostic imaging services (based on Procedure Code Sequence (0008,1032) or Procedure Code (TID 1005) values). The set of attributes is identical for the "Procedure" and "Act" Context.

Figure A.5.1.3-7. Procedure Context for Image-Guided Interventions

Figure A.5.1.3-7 and Figure A.5.1.3-8 show the procedure context for image-guided interventions and diagnostic imaging services and its relationship to CDA document sections plus quantity measurements. The component act relationship between Section and Procedure/Act is encoded as a section entry in CDA; QuantityMeasurement as an observation CDA entry and the component act relationship between Procedure/Act and QuantityMeasurement as entryRelationship.

##### A.5.1.4.3 Observer Context

The Observer Context (TID 1002) maps to the author participation and associated roles and entities at document or section level. DICOM specifies a Person Observer (TID 1003) and a Device Observer (TID 1004). Depending on the DICOM SR Observer Type, attribute values are mapped to the Person or AuthoringDevice Entity in the AuthorChoice Box.

The Person and Device Observer Context used at document level (Figure A.5.1.3-9) may be overridden at section level (Figure A.5.1.3-10).
