Mapping

This chapter describes the mapping between a DICOM SR Measurement Report and FHIR resources.

DICOM SR Measurement Report Mapping Overview

The mapping between DICOM SR Measurement Report contents and FHIR Resources is split into several sections as follows:

• DICOM SR Measurement Report Instance Mapping
• Document IE Mapping
• Imaging Measurements Container Mapping
• Imaging Measurement Group Mapping
• ​Imaging Measurement Mapping
• Imaging Qualitative Evaluation Mapping
• Derived Imaging Measurement Mapping

DICOM SR Measurement Report Instance Mapping

The DICOM SR Measurement Report instance contains the following information relevant to creating FHIR resources:

• The Patient IE used to associate created resources with the appropriate Patient
• The Study ID used to associated created resources with the appropriate ImagingStudy and ServiceRequest
• The General Equipment IE used to create a FHIR Device resource
• The Document IE is used to create one or more FHIR Observations

Note: This implementation guide assumes that Patient, ImagingStudy and ServiceRequest resources already exist in the destination FHIR server. See Other Resource Relationships.

Document IE Mapping

The DICOM SR Document IE contains:

• The PreliminaryFlag attribute which may indicate whether the contained observations are preliminary or final
• The ParticipantSequence attribute which may indicate:
  • A person who may be the performer of created observations
  • A device that may override the EquipmentDevice as the device associated with created observations
• The ContentSequence containing the SR content tree
  • The mapped content is from the Imaging Measurements CONTAINER node

See also the DICOM SR Document IE to FHIR ConceptMap.

Imaging Measurements Container Mapping

The Imaging Measurements Container contains:

• 0..1 Algorithm Identification content items
• 0..n MeasurementGroup Container nodes each of which maps to an ImagingMeasurementGroup Observation
• 0..1 Derived Imaging Measurements Containers
  • Each child node of this container maps to a DerivedImagingMeasurement Observation
• 0..1 Qualitative Evaluations Container
  • Select child nodes of this container maps to a ImagingQualitativeEvaluations Observation
    • Child nodes may include additional Algorithm Identification content items

See also the DICOM Imaging Measurements Container ConceptMap.

Imaging Measurement Group Mapping

The Imaging Measurement Group contains:

• 0..n Numerical Measurement Container nodes each of which maps to an ImagingMeasurement Observation
• 0..1 Algorithm Identification content items
• 0..1 Tracking Identifier content items
• 0..1 Tracking Unique Identifier content items
• 0..1 Finding content items representing the coded value of the imaging measurement group
• 0..1 Finding Category content items
• 0..1 Finding Site content items
  • Maps to a FindingSite BodyStructure
• 0..1 Image Region content items
  • Maps to an ImageRegion ImagingSelection
• 0..1 Measurement Method content items
