/// Representation of the content produced in a DICOM imaging study.
///
/// An ImagingStudy comprises a set of series, each of which includes a set of
/// Service-Object Pair Instances (SOP Instances - images or other data) acquired
/// or produced in a common context. A series is of only one modality (e.g.
/// X-ray, CT, MR, ultrasound), but a study may have multiple series of different
/// modalities. In FHIR R5 the resource is used to catalog imaging content and to
/// provide access endpoints for retrieval from PACS and other DICOM systems.
///
/// Clinically, an `ImagingStudy` acts as an index or manifest over DICOM
/// content: it does not embed pixel data itself, but instead describes the
/// study, series, and instance hierarchy along with identifiers (such as the
/// DICOM Study, Series, and SOP Instance UIDs) and network endpoints that
/// clients can use to retrieve the actual images from a PACS, VNA, or other
/// DICOM-capable system (for example via WADO-RS). This makes the resource
/// useful both for administrative tracking of imaging orders and results, and
/// for enabling downstream systems to locate and fetch imaging content without
/// duplicating large binary payloads inside the FHIR server.
///
/// Related resources: an `ImagingStudy` is typically ordered via a
/// `ServiceRequest`, references the imaged individual through `subject`
/// (commonly a [`Patient`](crate::r5::resources::patient::Patient)), may be
/// linked to an `Encounter`, and often produces or is referenced by an
/// `ImagingSelection` or `DiagnosticReport`. Modality and other coded values
/// on the study and its series use [`CodeableConcept`](crate::r5::types::CodeableConcept).
///
/// # Examples
///
/// ```
/// use fhir::r5::resources::imaging_study::ImagingStudy;
///
/// let value = ImagingStudy::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: ImagingStudy = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
/// ```
