--- title: FHIR ImagingStudy tags: fhir-resources --- <font color="red">FHIR</font> ImagingStudy === [TOC] ## Scope and Usage ImagingStudy provides information on a DICOM imaging study, and the series and imaging objects in that study. It also provides information on how to retrieve that information (in a native DICOM format, or in a rendered format, such as JPEG). ImagingStudy is used to make available information about all parts of a single DICOM study. ## How to store DICOM image information in FHIR ImagingStudy? **Step 1. Find a DICOM Web Server to store your image** You can use existing DICOM Web Server hosted by 3rd part or host your own DICOM Web Server. In this tutorial we are going to use 3rd party DICOM Web Server called [Orthanc](https://orthanc.dicom.tw). We are using the existing breast mammography image of this [dummy patient](https://orthanc.dicom.tw/app/explorer.html#patient?uuid=3de0818b-1f88ee30-575446ae-6a0320ee-699cc45b) **Step 2. Get image's Study, Series, and Instance UID** The mammography image differs into 4 series. Each series contains 1 instance. ![](https://i.imgur.com/EzfJmQ4.png) **Step 3. Create FHIR ImagingStudy and upload into FHIR Server** ```gherkin= { "resourceType": "ImagingStudy", "identifier": [ { "use": "official", "system": "urn:dicom:uid", "value": "urn:oid:1.2.1124.113532.134.0.1.3.20030423.143824.800378" } ], "status": "available", "modality": [ { "coding": [ { "system": "http://dicom.nema.org/resources/ontology/DCM", "code": "MG" } ] } ], "subject": { "reference": "Patient/1168613" }, "encounter": { "reference": "Encounter/6947773" }, "started": "2022-08-06T11:01:20+03:00", "basedOn": [ { "type": "ServiceRequest", "identifier": { "type": { "coding": [ { "system": "http://terminology.hl7.org/CodeSystem/v2-0203", "code": "ACSN" } ] } } }, { "reference": "ServiceRequest/6947777" } ], "referrer": { "reference": "Practitioner/example" }, "interpreter": [ { "reference": "Practitioner/radiologist" } ], "endpoint": [ { "reference": "Endpoint/example-wadors" } ], "numberOfSeries": 4, "numberOfInstances": 4, "series": [ { "uid": "1.2.1840.113681.2198909122.3931.3228559234.98.1", "number": 1, "modality": { "coding": [ { "system": "http://dicom.nema.org/resources/ontology/DCM", "code": "MG" } ] }, "description": "MG R CC", "numberOfInstances": 1, "performer": [ { "function": { "coding": [ { "system": "http://terminology.hl7.org/CodeSystem/v3-ParticipationType", "code": "PRF" } ] }, "actor": { "reference": "Practitioner/radiographer" } } ], "instance": [ { "uid": "1.2.1840.113681.2198909122.3931.3228559234.104.1", "sopClass": { "system": "urn:ietf:rfc:3986", "code": "urn:oid:1.2.840.10008.5.1.4.1.1.1.2" }, "number": 1 } ] }, { "uid": "1.2.1840.113681.2198909122.3931.3228559234.99.1", "number": 2, "modality": { "coding": [ { "system": "http://dicom.nema.org/resources/ontology/DCM", "code": "MG" } ] }, "description": "MG L CC", "numberOfInstances": 1, "performer": [ { "function": { "coding": [ { "system": "http://terminology.hl7.org/CodeSystem/v3-ParticipationType", "code": "PRF" } ] }, "actor": { "reference": "Practitioner/radiographer" } } ], "instance": [ { "uid": "1.2.1840.113681.2198909122.3931.3228559234.102.1", "sopClass": { "system": "urn:ietf:rfc:3986", "code": "urn:oid:1.2.840.10008.5.1.4.1.1.1.2" }, "number": 1 } ] }, { "uid": "1.2.1840.113681.2198909122.3931.3228559234.100.1", "number": 3, "modality": { "coding": [ { "system": "http://dicom.nema.org/resources/ontology/DCM", "code": "MG" } ] }, "description": "MG L MLO", "numberOfInstances": 1, "endpoint": [ { "reference": "Endpoint/example-wadors" } ], "performer": [ { "function": { "coding": [ { "system": "http://terminology.hl7.org/CodeSystem/v3-ParticipationType", "code": "PRF" } ] }, "actor": { "reference": "Practitioner/radiographer" } } ], "instance": [ { "uid": "1.2.1840.113681.2198909122.3931.3228559234.106.1", "sopClass": { "system": "urn:ietf:rfc:3986", "code": "urn:oid:1.2.840.10008.5.1.4.1.1.1.2" }, "number": 1 } ] }, { "uid": "1.2.1840.113681.2198909122.3931.3228559234.101.1", "number": 4, "modality": { "coding": [ { "system": "http://dicom.nema.org/resources/ontology/DCM", "code": "MG" } ] }, "description": "MG R MLO", "numberOfInstances": 1, "performer": [ { "function": { "coding": [ { "system": "http://terminology.hl7.org/CodeSystem/v3-ParticipationType", "code": "PRF" } ] }, "actor": { "reference": "Practitioner/radiographer" } } ], "instance": [ { "uid": "1.2.1840.113681.2198909122.3931.3228559234.108.1", "sopClass": { "system": "urn:ietf:rfc:3986", "code": "urn:oid:1.2.840.10008.5.1.4.1.1.1.2" }, "number": 1 } ] } ] } ``` [url: https://hapi.fhir.org/baseR4/ImagingStudy/misac-example-mg](https://hapi.fhir.org/baseR4/ImagingStudy/misac.dicom.image01) **Step 4. Retrieve the DICOM image URL** We can retrieve a DICOM image on DICOM web server with WADO-URI format. WADO-URI format: <font style="color:orange">[dicom server endpoint]</font>/?requestType=WADO&<font style="color:red">studyUID=[your study UID]</font>&<font style="color:green">seriesUID=[your series UID]</font>&<font style="color:blue">objectUID=[your instance UID]</font>&contentType=application/dicom</td> Example: [<font style="color:orange">https://orthanc.dicom.tw</font>/wado/?requestType=WADO&<font style="color:red">studyUID=1.2.1124.113532.134.0.1.3.20030423.143824.800378</font>& <font style="color:green">seriesUID=1.2.1840.113681.2198909122.3931.3228559234.99.1</font>&<font style="color:blue">objectUID=1.2.1840.113681.2198909122.3931.3228559234.102.1</font>&contentType=application/dicom</td>](https://orthanc.dicom.tw/wado/?requestType=WADO&studyUID=1.2.1124.113532.134.0.1.3.20030423.143824.800378&seriesUID=1.2.1840.113681.2198909122.3931.3228559234.99.1&objectUID=1.2.1840.113681.2198909122.3931.3228559234.102.1&contentType=application/dicom) If you click on the example WADO url above, it will download a dicom file, where this file will be use to display image into the image viewer. ## References * [HL7 FHIR ImagingStudy](https://build.fhir.org/imagingstudy.html) * [WADO-URI](http://dicomcloud.com/docs/dicomcloud/wadouri/)
