3. ChRIS plugin PACS query workflow
This page describes interacting with the ChRIS Ultron Back End (CUBE) using pfurl
and running an FS
type plugin called pl-pacsquery
. Essentially, pl-pacsquery
searches a PACS for some meta information based on a pattern of command line terms, and returns results of this query in several small text/JSON files.
You should set an environment variable, HOST_IP
to the IP of the actual host you are using. In Linux, this is
export HOST_IP=$(ip route | grep -v docker | awk '{if(NF==11) print $9}')

Start CUBE from the repository source directory, running
*make*
A PACS server should be accessible via IP:port to this plugin, i.e. a network path must exist between the plugin (and the host/container where it runs) and a PACS server.
In the CUBE system, we use an Orthanc container to simulate a PACS. Starting this server is out of scope of this document. See elsewhere for more information.

Look through the list for pl-pacsquery
. For example, let's say that this is located at
http://10.17.24.163:8000/api/v1/plugins/3/
we can call
pfurl --auth chris:chris1234 --http ${HOST_IP}:8000/api/v1/plugins/3/ \
