1 -- This sample shows how to invoke an ImageJ script on every DICOM
2 -- image received by Orthanc. The ImageJ script is generated by the
3 -- "Initialize()" function at the startup of Orthanc. Whenever a new
4 -- instance is received, its DICOM file is stored into a temporary
5 -- file, and a system call to ImageJ is triggered.
