-- This sample shows how to invoke an ImageJ script on every DICOM -- image received by Orthanc. The ImageJ script is generated by the -- "Initialize()" function at the startup of Orthanc. Whenever a new -- instance is received, its DICOM file is stored into a temporary -- file, and a system call to ImageJ is triggered. SCRIPT = 'ImageJScript.txt' function Initialize() local target = assert(io.open(SCRIPT, 'w')) -- This is a sample ImageJ script that display the size of the DICOM image target:write('if (getArgument=="") exit ("No argument!");\n') target:write('open(getArgument);\n') target:write('print(getTitle + ": " + getWidth + "x" + getHeight);\n') target:close() end function OnStoredInstance(instanceId) -- Retrieve the DICOM instance from Orthanc local dicom = RestApiGet('/instances/' .. instanceId .. '/file') -- Write the DICOM content to some temporary file local path = instanceId .. '.dcm' local target = assert(io.open(path, 'wb')) target:write(dicom) target:close() -- Call ImageJ os.execute('imagej -b ' .. SCRIPT .. ' ' .. path) -- Remove the temporary DICOM file os.remove(path) end
