Comments

Element ImagingSelection.instance is not mapped to FHIR R4, since FHIR R5 ImagingSelection is not mapped. Element ImagingSelection.instance has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element).

Definition

An Extension


May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

Comments

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

      An Extension


      May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

      Comments

      There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

                  ShortR5: DICOM Instance Number (new)
                  Comments

                  Element ImagingSelection.instance.number is part of an existing definition because parent element ImagingSelection.instance requires a cross-version extension. Element ImagingSelection.instance.number is not mapped to FHIR R4, since FHIR R5 ImagingSelection is not mapped. Element ImagingSelection.instance.number has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). See DICOM PS3.3 C.7.6.1. Note: A multiframe instance has a single instance number with each frame identified by a frame number.

                  There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

                                    The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.
