HHH.3.2 Analysis of Use Cases

Examples of use cases / clinical scenarios, as the basis to develop the requirements, include:

Examples of the use cases described in 1 above are:

  1. The EMR displays in JPEG one image with annotations on it (patient and/or technique related), based upon information provided in a report.

  2. The EMR retrieves from a "Manifest" document all the referenced objects in DICOM and launches a DICOM viewer for displaying them (use case addressed by the IHE XDS-I.b profile).

  3. The EMR displays in JPEG one image per series with information describing every series (e.g., series description).

  4. The EMR displays in JPEG all the images of a series with information describing the series as well as every image (e.g., instance number and slice location for scanner images).

  5. The EMR populates in its database for all the instances referred in a manifest (KOS) the relevant information (study ID/UID/AccessionNumber/Description/DateTime, series UID/Modality/Description/DateTime, instance UID/InstanceNumber/SliceLocation).

  6. The EMR displays patient demographics and image slices in a browser by accessing studies through URLs that are cached and rendered in a remote data center.

  7. A hospital transfers a DICOM Study over a network to another healthcare provider without needing special ports opened in either firewall.

  8. A diagnostic visualization client, during post-processing, adds a series of Instances containing measurements, annotations, or reports.

  9. A healthcare provider transfers a DICOM Study to a Patient Health Record (PHR) at the request of the patient.

As an example, the 1c use case is decomposed in the following steps (all the other use cases can be implemented through a similar sequence of basic transactions):

  1. The EMR sends to the DICOM server the list of the objects ("selection"), asking for the object content.

  2. The DICOM server sends back the JPEG images corresponding to the listed objects.

  3. The EMR sends to the DICOM server the "selection" information for obtaining the relevant information about the objects retrieved.

  4. The DICOM server sends back the corresponding information in the form of a "metadata" document, converted in XML.
