Todo list

1.

Performance

• Increase rendering speed(fixing 1d texture mapping, playing around wtk,etc.)(1)

• Reduce the start up time. Profile the program (1)

• Re-engineer the code to make it more readable and maintainable.(1)

2.

Data

• Bring the new data in
  • add cortical surface, blood vessels, tumor growth direction, CSF surfaces inside sulci, etc. as they arrive.(1)
  • Get OCD data in the cave, use Peter Basser's brain data for now(1)
  • Should follow up with Carlo Pierpaoli to get pre- and post- gamma capsulotomy DT-MRI's. . The first goal is to figure out how far from the gamma knife lesion we can see changes in the various pathways going through the anterior limb of the internal capsule. Doctors(B.Green) think that the thalamus - cortex connections, which are reciprocal and excitatory, are the key, but there may well be others that are important in the therapeutic response. Any change we could see could be important. - B. Green will help us if we need him to (2)

• Take some data out
  • Lose top half(?)
  • Lose left/right side(?)
  • Lose ventricles entirely - with T2 slices? (?)

3.

Interface

• Create a better pointer - needs to highlight where it hits things (a small sphere?) and possibly not continue past that point, much like a real laser pointer. This should be coordinated with picking for selecting geometric objects and for making them visible/invisible.(1)

• User should be able to change the parameter. Consider a threshold criterion based on how curved the tubes are.(2)

• Ability to add/remove the models (tubes, surfaces, ventricles) individually and to choose only tubes/surfaces through some particular geometry(ies).(2)
• Need a way to interactively change what's on the 2D sections - T1, T2, T1+gad, etc. (1)

• Let the user work on tumor more freely.(2)
• Change sliding interface. Make able to rotate the volume(with geoms) at least for showing brain supine. (3)
• Surgeon would really be able to see through a craniotomy (3)
• Look at BrainSight software (http://www.rogue-research.com/ ) to study it for interface ideas. Perhaps give the group a demo. - Song (2)
• morphometric abilities - measuring lengths between features (e.g., tract/tumor, vessel/tumor, vessel/tract) and volumes (2)
• implementing microscope or magnifier metaphor(4)
• simple voice recognition and haptic interfaces(5)

4.

Misc.

• Go to 100% size of brain to see how it works, this might also help the slice resolution look better(1)
• Need to deal with strength of anisotropy as well as directional/path changes.(?)
• Framerate sensitive geometric displaying. Dynamically determine which geometric models to load by measuring current fps.(sz 3.22.01)
• Multithread streamtubes generating.(sz 3.22.01)
