Thanks to the REST API of Orthanc, it is easy to access DICOM images from Matlab or Octave, as depicted in the following sample image:
Both Matlab and Octave have access to HTTP servers thanks to their built-in urlread() function. Once must simply install a Matlab/Octave library to decode JSON files. The JSONLab toolkit works perfectly to this end.
Using JSONlab, the following code will download and display a DICOM image:
SERIES = 'ae164c84-e5bd0366-ba937a6d-65414092-f294d6b6'; URL = 'http://demo.orthanc-server.com/'; # Get information about the instances in this DICOM series instances = loadjson(urlread([ URL '/series/' SERIES '/instances' ])); # Select one slice from the series instance = instances(1,1).ID # Decode the slice with Orthanc thanks to the "/matlab" URI slice = eval(urlread([ URL '/instances/' instance '/matlab' ])); # Compute the maximum value in this slice max(max(slice)) # Display the slice imagesc(slice) # Annotate the graph with the patient name and ID tags = loadjson(urlread([ URL '/instances/' instance '/tags?simplify' ])); title([ 'This is a slice from patient ' tags.PatientID ' (' tags.PatientName ')' ])
