Query data in the Orthanc server

Usage

query_orthanc(
  client,
  level,
  query = list(),
  labels = character(),
  labels_constraint = "All",
  limit = 1000L,
  since = 0L,
  retrieve_all_resources = TRUE,
  lock_children = FALSE
)

Arguments

client: Orthanc API client.
level: Level of the query ('Patient', 'Study', 'Series', 'Instance').
query: Named-list that specifies the filters on the level related DICOM tags.
labels: Character vector of labels to look for in resources.
labels_constraint: Contraint on the labels ('All', 'Any', 'None').
limit: Limit the number of reported instances (default is 1000L).
since: Show only the resources since the index specified in the since parameter.
retrieve_all_resources: Retrieve all resources since the index specified in the since parameter.
lock_children: If lock_children is TRUE, the resource children (e.g., instances of a series via Series.instances) will be cached at the first query rather than queried every time. This is useful when you want to filter the children of a resource and want to maintain the filter result.

Value

A list of resources.
