receive data from arrayBuffer by using XTK

Question

I'm trying to use XTK to load DICOM files, by using the following code:

var _dicom = ['1','2','3']
volume.file = _dicom.sort().map(function(v) {
   return 'data/path/' + v + '.DCM';
});

The Output:

is an arrayBuffer

I would like to know how to read the arrayBuffer and render it. I tried volume.filedata = dataFromArrayBuffer, but it does not work.
