Application View

There are different implementation options, not mutually exclusive, for searching and retrieving Imaging Study information:

  1. searching per HL7 FHIR ImagingStudy
  2. searching per DICOM Study metadata

Implementation details are given in the linked pages.

It is not listed here the case of a document including study information, since this case falls into the Search and Get Documents case.

Searching per HL7 FHIR ImagingStudy

In the first case Imaging Study information are shared by using an HL7 FHIR ImagingStudy resource.

Accoridng to the HL7 FHIR standard infact an ImagingStudy is a "Representation of the content produced in a DICOM imaging study. <…> An ImagingStudy SHALL reference one DICOM Study, and MAY reference a subset of that Study. More than one ImagingStudy MAY reference the same DICOM Study or different subsets of the same DICOM Study. ".

Specifications in the Get Study Metadata (HL7 FHIR) page

Searching per DICOM Study

In the second case a DICOMWeb call it is used to query the NCPeH. A DICOM Conformance Statement describing how to realize this in MyHealth@EU is given in the Study Information Retrieval page.

In IHE terms this refers to the Retrieve [RAD-107] transaction (see Section 4.107 IHE RAD TF Vol 2.

In both cases the NCPeH API acts as a "facade" over the National Infrastructure, how studies are made available for cross border sharing depends on the national infrastructure.

The user gets from the document and/or the study infos all the identifiers of the evidences belonging to the study or referred by the document.

Optionally he/she selects the level from which retrieve the instances (study, series, instance). That is all the instacne belonging to this study/seris or this list of instances.

Once known the relevant DICOM identifiers DICOM WADO-RS is used to retrieve

  • All instances of a Study (getImages-sequence.html)
  • All instances of a Series (getImages-sequence.html)
  • All listed instances (getImages-sequence.html)

A DICOM Confrmance Statement describing how to realize this in MyHealth@EU is given in the Get Images page
