Gesundheitsdaten mit Clientbibliotheken speichern

Auf dieser Seite erfahren Sie, wie Sie mit der Cloud Healthcare API und den Clientbibliotheken für Google APIs die folgenden Aufgaben ausführen:

ein Cloud Healthcare API-Dataset erstellen
Erstellen Sie einen der folgenden Datenspeicher im Dataset:

DICOM-Speicher (Digital Imaging and Communications in Medicine)
FHIR-Speicher (Fast Healthcare Interoperability Resources)
Health Level Seven International Version 2-Speicher (HL7v2)

Bestimmte Arten von medizinischen Daten im DICOM-, FHIR- oder HL7v2-Speicher speichern und prüfen

Wenn Sie nur mit einem Datenspeichertyp arbeiten möchten, können Sie mit diesem Abschnitt der Kurzanleitung direkt fortfahren, nachdem Sie die Schritte in Vorbereitung und Ein Dataset erstellen ausgeführt haben.

Nachdem Sie eine DICOM-Instanz in der Cloud Healthcare API gespeichert und angezeigt haben, fahren Sie mit dem Abschnitt Bereinigen fort, um zu vermeiden, dass Ihrem Google Cloud-Konto die auf dieser Seite verwendeten Ressourcen in Rechnung gestellt werden.

Weitere Informationen zum Arbeiten mit DICOM-Daten finden Sie unter Nächste Schritte.

FHIR-Ressourcen speichern und ansehen

In diesem Abschnitt wird beschrieben, wie Sie die folgenden Aufgaben ausführen:

Erstellen Sie einen FHIR-Speicher.
Speichern Sie eine FHIR-Ressource im FHIR-Speicher.
Sehen Sie sich die Daten zur FHIR-Ressource an.

Die Cloud Healthcare API implementiert den Standard von FHIR-Spezifikation zum Speichern und Zugreifen auf FHIR-Daten.

FHIR-Speicher erstellen

FHIR-Speicher sind in Datasets vorhanden und enthalten FHIR-Ressourcen. Führen Sie folgenden Befehl aus: um einen FHIR-Speicher zu erstellen.

Entfernen Sie vor dem Ausführen der Beispiele die Kommentarzeichen und geben Sie gegebenenfalls die folgenden Werte an:

die ID des Google Cloud-Projekts, das Sie unter Vorbereitung erstellt oder ausgewählt haben

Nach dem Speichern und Anzeigen einer HL7v2-Nachricht in der Cloud Healthcare API Fahren Sie mit dem Abschnitt Bereinigen fort, damit keine Gebühren für Ihr Google Cloud-Konto für die auf dieser Seite verwendeten Ressourcen.

Weitere Informationen zum Arbeiten mit HL7v2-Daten finden Sie unter Nächste Schritte.

Bereinigen

Löschen Sie das Google Cloud-Projekt mit den Ressourcen, damit Ihrem Google Cloud-Konto die auf dieser Seite verwendeten Ressourcen nicht in Rechnung gestellt werden.

Wenn Sie ein neues Projekt für diese Kurzanleitung erstellt haben, führen Sie die Schritte unter Projekt löschen aus. Andernfalls führen Sie die Schritte unter Dataset löschen aus.

Optional: Revoke the authentication credentials that you created, and delete the local credential file.
```
gcloud auth application-default revoke
```
Optional: Revoke credentials from the gcloud CLI.
```
gcloud auth revoke
```

Projekt löschen

Achtung: Das Löschen von Projekten hat folgende Auswirkungen:

Alle Inhalte des Projekts werden gelöscht. Wenn Sie für die Aufgaben in diesem Dokument ein bereits bestehendes Projekt verwendet haben und dieses löschen, werden auch alle anderen im Rahmen des Projekts erstellten Daten gelöscht.
Benutzerdefinierte Projekt-IDs gehen verloren. Beim Erstellen dieses Projekts haben Sie möglicherweise eine benutzerdefinierte Projekt-ID erstellt, die Sie weiterhin verwenden möchten. Damit die URLs, die die Projekt-ID nutzen, z. B. eine appspot.com-URL, erhalten bleiben, sollten Sie ausgewählte Ressourcen innerhalb des Projekts löschen, statt das gesamte Projekt.

Wenn Sie mehrere Architekturen, Anleitungen und Kurzanleitungen durcharbeiten möchten, können Sie die Überschreitung von Projektkontingenten verhindern, indem Sie Projekte wiederverwenden.

Delete a Google Cloud project:

gcloud projects delete PROJECT_ID

Dataset löschen

Wenn Sie das in dieser Kurzanleitung erstellte Dataset nicht mehr benötigen, können Sie es löschen. Durch das Löschen eines Datasets werden das Dataset und alle darin enthaltenen FHIR-, HL7v2- oder DICOM-Speicher endgültig gelöscht.

Entfernen Sie vor dem Ausführen der Beispiele die Kommentarzeichen und geben Sie gegebenenfalls die folgenden Werte an:

die ID des Google Cloud-Projekts, das Sie unter Vorbereitung erstellt oder ausgewählt haben
my-dataset für die Dataset-ID
us-central1 für den Speicherort des Datasets
