Comments from Ari Blitz, 20/4

• I still wonder whether somehow changing the orientation of the brain (perhaps with the glove) might be useful.
• It occurs to me that we might find a floating display, fixed with respect to head position, useful. For example I might include several flat frames arranged vertically off to the side of the 3d image.
  • the T2 MRI slice currently selected without DTI info superimposed.
  • the T2 MRI slice with 2D DTI info superimposed [Note: both seem important as deep structures are hidden by 3d display]
  • identifying information such as the name of data set and thresholding information on what is being display in 3D. If 3D DTI display finds clinical application by practicing neuroradiologists in ? years I suspect something like this will be necessary. More importantly I think it might be useful in deciding what we are looking at in the short term.
• Could there be an interface involving the glove or pointer which allowed the user to choose among preset thresholding of the data displayed in 3d?
• It would be nice if we could freeze the image and print out a "3d" image with annotation similar to those in your streamtubes paper.
• Purely out of curiosity: how difficult or easy would it be to print out a frozen image of what we see in the CAVE which could be viewed with something like those old red-green 3d horror flick glasses or the old stereoviewers?
