description: Provides guidance as to which ImagingStudy attributes should be present and considerations as to how each attribute should be valued in all [FHIR resource]-close events.\n\nIt is recommended that the image study business identifiers provided in the corresponding [FHIR resource]-open event are provided in the [FHIR resource]-close event. Providing these business identifiers enables Subscribers to perform identity verification according to their requirements. See [FHIRcast ImagingStudy for Open Events](StructureDefinition-fhircast-imaging-study-open.html) for details on the business identifiers of an ImagingStudy. package_name: hl7.fhir.uv.fhircast derivation: constraint name: FHIRcastImagingStudyClose type: ImagingStudy elements: id: {short: A logical id of the resource SHALL be provided., index: 0} identifier: {short: 'At least one business identifier of the ImagingStudy SHOULD be provided in a [FHIR resource]-close request (see detailed description).', mustSupport: true, index: 1} status: {short: 'Status of the ImagingStudy, note this may be not be known and hence have a value of `unknown`; however, `status` is included since it is required by the FHIRcast', index: 2} subject: type: Reference short: Reference to the Patient resource associated with the ImagingStudy (see detailed description if the image study's subject is not a patient) refers: ['http://hl7.org/fhir/StructureDefinition/Device', 'http://hl7.org/fhir/StructureDefinition/Group', 'http://hl7.org/fhir/uv/fhircast/StructureDefinition/fhircast-patient-close'] index: 3 package_version: 3.0.0-ballot class: profile kind: resource url: http://hl7.org/fhir/uv/fhircast/StructureDefinition/fhircast-imaging-study-close base: http://hl7.org/fhir/StructureDefinition/ImagingStudy version: 3.0.0-ballot required: [id]
