Mobile Access to DICOM Objects (MADO)
0.1.0-SNAPSHOT - ci-build International flag

Mobile 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-SNAPSHOT built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/bvdh/bvdh-ihe-mado/ and changes regularly. See the Directory of published versions

FHIR Imaging Manifest

The FHIR imaging manifest represents a summary of the data stored in a DICOM imaging study as is stored in a PACS expressed in FHIR. It is the FHIR equivalent of the DICOM KOS manifest. It is the 'document' that is searched for and provides the URL's that allow download of the imaging content.

FHIR Manifest overview

The figure below presents an overview of the data that is part of the imaging-manifest. In order to keep the diagram readable, not all references are included.

Figure: FHIR Manifest Overview

The manifest is a FHIR bundle that SHALL conform to the MADO FHIR Bundle profile. This Bundle includes the MADO FHIR ImagingStudy resource, the , at least one Endpoint and additional resources. The Bundle SHALL contain all available data elements in the FHIR column in Table 4.3-1 (see DICOM KOS <-> FHIR mappings).

Feedback is requested from the implementer community whether we need to highlight these fields more explicitly and how (e.g. using FHIR obligations).

Endpoint resources contain the information that allows the client to access the DICOM data. The current model identifies two different Endpoints:

The profile provides information on the system that generated the manifest.

Besides the ImagingStudy and Endpoint resources, also additional resources are present that reflect information present in DICOM such as information on the patient, performer, procedure and imaging device. What resources to include depends on the information to be included, see DICOM KOS <-> FHIR mappings for more information on when to include what resource.

The following links are provided for convenience.

NameTitleDescription
MadoAccessionNumberIdentifier

MADO Accession Number Identifier

Profile for the Accession Number Identifier used in the MADO context. This profile is used for the Identifier that represents the Accession Number in the MADO context. It includes additional constraints and extensions specific to the MADO context, such as the value set for the type of identifier and the fixed value for the system of the identifier.

MadoAnatomicalRegionExtension

Extension: Anatomical Region

The anatomical region in an ImagingStudy instance. This is additional information next to ImagingStudy.series.bodySite.

MadoCreator

MADO Creator

A profile for the Device resource that represents the creator of an ImagingStudy in the MADO context. This profile is used for the Device resource that represents the author of an ImagingStudy in the MADO context.

MadoCreatorExtension

Extension: Creator of the MADO

The creator of the MADO, which is the device that created the ImagingStudy resource in the MADO context.

MadoFhirBundle

MADO FHIR Bundle

Profile for FHIR Bundles used in the MADO context. This profile is used for the FHIR Bundles that represent imaging manifests using the DICOM KOS format in the MADO context. It includes additional constraints and extensions specific to imaging manifests, such as the type of report, the clinical specialty, and the anatomical region of interest.

MadoImagingStudy

MADO Imaging Study

Profile for ImagingStudy resources used in the MADO context. This profile is used for the ImagingStudy resources that represent the imaging studies in the MADO context. It includes additional constraints and extensions specific to the MADO context, such as the type of imaging study, the clinical specialty, and the anatomical region of interest.

MadoNumberOfFrames

Extension: Number of Frames

The number of frames in an ImagingStudy instance.

MadoReferencedAccessionNumberIdentifier

MADO Referenced Accession Number Identifier

Profile for the Reference that contains the Accession Number Identifier used in the MADO context. This profile is used for the Reference that contains the Identifier that represents the Accession Number in the MADO context. It includes additional constraints and extensions specific to the MADO context, such as the value set for the type of identifier and the fixed value for the system of the identifier.

MadoReferencedStudyInstanceUidIdentifier

MADO Referenced Study Instance UID Identifier

Profile for the Reference that contains the Study Instance UID Identifier used in the MADO context. This profile is used for the Reference that contains the Identifier that represents the Study Instance UID in the MADO context. It includes additional constraints and extensions specific to the MADO context, such as the value set for the type of identifier and the fixed value for the system of the identifier.

MadoRepresentativeInstanceExtension

Extension: Representative Instance

An extension to indicate that a referenced instance on and ImagingStudy series is a representative instance for that series. This extension is used in the MADO context to indicate that a referenced instance on an ImagingStudy series is a representative instance for that series, which can be used for display purposes in the MADO context.

MadoStudyInstanceUidIdentifier

MADO Study Instance UID Identifier

Profile for the Study Instance UID Identifier used in the MADO context. This profile is used for the Identifier that represents the Study Instance UID in the MADO context. It includes additional constraints and extensions specific to the MADO context, such as the value set for the type of identifier and the fixed value for the system of the identifier.

MadoWadoEndpoint

Endpoint: WADO

This profile defines the WADO endpoint for accessing imaging study content.

MadoXcWadoEndpoint

Endpoint: IHE-XC-WADO

This profile defines the XC-WADO endpoint for accessing imaging study content. It is a regular WADO endpoint with an additional extension that holds the locationUID of the domain where the content can be accessed. See the IHE XC-WADO specification for more details. Note that in XC-WADO the address is optional. When no address is known, a placeholder value is inserted and a data absent exception with the code not-applicable.

XcWadoLocationUIDExtension

Extension: Location UID

The location UID of the source of the WADO URL. See XC-WADO and https://dicom.nema.org/medical/dicom/current/output/chtml/part03/sect_A.35.4.3.html#table_A.35.4-1.
