description | Das AT APS-Profil für die ImagingStudy-Ressource berücksichtigt zum einen die österreichischen Vorgaben (z.B. Patient und zu verwendende Value-Sets) und stellt andererseits die Konformität gegenüber dem IPS-Profil sicher, indem die so genannte [`imposeProfile`](http://hl7.org/fhir/StructureDefinition/structuredefinition-imposeProfile)-Erweiterung verwendet wird. |
