HealthImaging-Beispiele unter Verwendung von SDK für Python (Boto3) - AWS-SDK-Codebeispiele

Weitere AWS-SDK-Beispiele sind im GitHub-Repository Beispiele für AWS Doc SDKs verfügbar.

HealthImaging-Beispiele unter Verwendung von SDK für Python (Boto3)

Die folgenden Codebeispiele zeigen, wie Sie Aktionen durchführen und gängige Szenarien implementieren, indem Sie AWS SDK für Python (Boto3) mit HealthImaging nutzen.

Aktionen sind Codeauszüge aus größeren Programmen und müssen im Kontext ausgeführt werden. Während Aktionen Ihnen zeigen, wie Sie einzelne Servicefunktionen aufrufen, können Sie Aktionen im Kontext der zugehörigen Szenarien anzeigen.

Szenarien sind Codebeispiele, die Ihnen zeigen, wie Sie bestimmte Aufgaben ausführen, indem Sie mehrere Funktionen innerhalb eines Services aufrufen oder mit anderen AWS-Services kombinieren.

Jedes Beispiel enthält einen Link zum vollständigen Quellcode, wo Sie Anweisungen zum Einrichten und Ausführen des Codes im Kodex finden.

Szenarien

Das folgende Codebeispiel zeigt, wie Sie DICOM-Dateien importieren und Bild-Frames in HealthImaging herunterladen.

Die Implementierung ist als Befehlszeilenanwendung strukturiert.

  • Richten Sie Ressourcen für einen DICOM-Import ein.

  • Importieren Sie DICOM-Dateien in einen Datenspeicher.

  • Rufen Sie die Bildsatz-IDs für den Importauftrag ab.

  • Rufen Sie die Bild-Frame-IDs für den Importauftrag ab.

  • Laden Sie die Bild-Frames herunter, dekodieren Sie sie und überprüfen Sie sie.

  • Bereinigen Sie die Ressourcen.
