EHDS Logical Information Models, published by Xt-EHR. This guide is not an authorized publication; it is the continuous build for version 0.2.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/Xt-EHR/xt-ehr-common/ and changes regularly. See the Directory of published versions

Logical Model: Imaging study model

Official URL: https://www.xt-ehr.eu/specifications/fhir/StructureDefinition/EHDSImagingStudy Version: 0.2.0
Draft as of 2025-09-24 Computable Name: EHDSImagingStudy

Imaging study model includes the key information about the content of an imaging study. It does not include image pixels but includes location pointers to its image content and organises this information according to the well-established model of an imaging study made of one or more series and each series made of instances or images. Composed of a set of data (DICOM KOS) that facilitates the location of all available images.
