  title: Amazon HealthImaging Inspect Image Set
  summary: Read image set properties, fetch its metadata, then retrieve an image frame.
  description: >-
    Drills into a single image set from properties down to pixel data. The
    workflow reads the image set properties to confirm it is ACTIVE, fetches the
    aggregated DICOM metadata blob, and then retrieves a specific image frame
    (pixel data) by its frame identifier. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
