  • The Volumes Module loads, saves and adjusts display parameters of volume data.
  • Load
    • select the volume that you want to load
    • If needed edit the name that will be displayed for this volume inside slicer
    • If your volume is not a nrrd or dicom format, select "centered" for image origin, else select "from file".
    • If this is a label map, click the box
    • Active Volume: determines which volume is manipulated by the Display section. Make sure that you select the Volume that you intend to work on!
  • Display
    • Allows you to adjust the way that a volume is displayed
    • Window/Level can be set manually or automatically.
    • Threshold is a way to make the background black disappear in the 3D view, when slices are turned to visible.
    • For labelmaps you can select here the proper look-up table through the Color Select pull-down.
    • For DWI volumes you can select a component of the volume to visualize.
    • For DWI volumes you can edit the gradient directions and measurement frame using the DWI & DTI Editor described below.
    • For DTI volumes you can select a scalar drived component of the tensor volume (such as FA) to visualize.
    • For DTI volumes you can control the tensor glyphs visualization on the slice planes using the Glyph On Slices Display editor described below.
  • DWI & DTI Editor
    • For DWI
      • you can edit gradients manually or load existing gradients from file (.txt or .nhdr).
      • you can edit the measurement frame manually or simply rotate/swap/negate columns by selecting them.
      • you can do some testing with the parameters by estimating a tensor and displaying glyphs and tracts.
    • For DTI
      • you can edit the measurement frame as described above.
      • you can do some testing with displaying glyphs and tracts.
  • Glyph On Slices Display editor
    • Controls the tensor glyphs visibility on individual slices in both 3D and 2D viewers.
    • Selects the scalar to color the glyphs by and the color map to apply.
    • Controls glyphs opacity, glyph type, scale and sampling rate.
  • Info
    • Provides some basic information about the Volume
  • Save
    • Lets you save a volume. Make sure to provide an extension (such as myvolume.nrrd)
