orthanctool

orthanctool

Command line utility to interact with the Orthanc DICOM server.

Usage

$ orthanctool help
Usage: orthanctool <flags> <subcommand> <subcommand args>

Subcommands:
	changes          yield change entries
	clone            create a complete copy of all instances in an orthanc installation
	recent-patients  yield patient details for most recently changed patients

Clone

$ ./orthanctool help clone
clone --orthanc <source_url> --dest <dest_url>:
	copy all instances from <source> at the orthanc installation at <dest>.

  -dest value
    	destination Orthanc URL
  -orthanc value
    	source Orthanc URL
  -poll-interval int
    	poll interval in seconds (default 60)

$ orthanctool clone --orthanc http://A.example/ --dest http://B.example/

This copies all instances from A to B. It also watches A for changes and copies new instances as soon as they are added.

Recent Patients

$ orthanctool help recent-patients
recent-patients --orthanc <url> [command...]:
	Iterates over all patients stored in Orthanc roughly in most recently changed order.
	Outputs JSON with patient ID and LastUpdate timestamp.
	If <command> is given, it will be run for each patient and JSON will be passed to it via stdin.

  -orthanc value
    	Orthanc URL
  -poll int
    	poll interval in seconds. Set to 0 to disable polling) (default 60)

Patient JSON has the following format:

{
  "ID": "91b03ffc-e3672d12-988ec655-8e8e7d16-b28d78ec",
  "LastUpdate": "20170215T082242",
  "Remaining": 0
}

When a handler is given in the command line arguments, recent-patients executes that command for each patient and passes JSON via stdin. This passes every patient through jq, for example:

$ orthanctool recent-patients --orthanc http://A.example/ jq -c '.ID' | head -n 1
"ba5e828d-8d3a73da-40eead54-a5b26022-38f56659"

When --poll is true (default) then recent-patients will watch for changes and yield new patients as soon as they are stable.

Changes

$ ./orthanctool help changes
changes --orthanc <url> [--all] [--poll] [--sweep=<seconds>] [command...]:
	Iterates over changes in Orthanc.
	Outputs each change as JSON.
	If command is given, it will be run for each change and JSON will be passed to it via stdin.

  -all

  -filter string
    	only output changes of this type
  -orthanc value
