title: file conversion layers to volume
body: <p>in the field of radiology there are many ways to scan a part or even the whole body. i need to convert many medical dicom-files (&gt; 100 layers) to one volume file to transfer a 3d-volume instead of 2d-data.
  one format is the <strong>.nrrd</strong> format used here:</p>

  <p>i know there is <a href="http://www.slicer.org/" rel="nofollow noreferrer">slicer</a> but is there another way to convert the files? did anybody come across this?</p>
  <p>thanks in advance</p>
