  title: Amazon HealthImaging Find Image Set by Patient
  summary: Search image sets by DICOM patient ID, then read the top match's properties and metadata.
  description: >-
    Locates a patient's imaging data and drills into the first match. The
    workflow searches the data store using an EQUAL filter on the DICOM patient
    ID, branches on whether any image set was found, and when a match exists
    reads its properties and downloads its metadata blob. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.

  summary: Search for a patient's image set and inspect the first result.
  description: >-
    Runs a patient-ID search against the data store, and when at least one image
    set is returned, reads the first match's properties and fetches its metadata
    blob.
