Mappings between MADO FHIR and MADO DICOM KOS

Manifest-based Access to DICOM Objects (MADO)
0.1.0 - trial-use International flag

Manifest-based Access to DICOM Objects (MADO), published by IHE Radiology Technical Committee. This guide is not an authorized publication; it is the continuous build for version 0.1.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/IHE/RAD.MADO/ and changes regularly. See the Directory of published versions

The mapping between the DICOM KOS and FHIR format is presented in the table below. In order to make it clear what concept is addressed, the first column contains a short characterization of the concept. The other two columns show the corresponding FHIR and DICOM KOS fields. In the case that more than one field is presented, it is expected that the concept will be present in each of them.

In the FHIR column, the expression Resource.field1.field2 means within the resource Resource, there is an element called field1 that contains the element field2. The expression field1->resource means that field1 is reference that points to the resource resource.

In the KOS column the expression sequence->field means that within the sequence sequence there is a field called field. The expression SR:EV(aaa,DCM,"name")->EV(bbb,DCM,"name") means that within the DICOM SR ContentSequence there is a SR node with the code aaa that contains the SR node bbb.

Please note that in this table:

Multiplicities are not indicated nor implied. Please refer to the base DICOM KOS Manifest or FHIR Imaging Study Manifest for information on multiplicities.
The intention of this table is present the location in the FHIR/DICOM manifest where the corresponding information element can be found. It is not intended as a definition on the construction of the FHIR/DICOM KOS manifest. In the case of discrepancies, the definitions of these formats have prevalence.
In the case that for a concept the table lists multiple locations, this means that the same value is present at each location. Instances where those data elements differ are malformed.
