Firstly, we are intending to acquire an Onyx IR soon.
We have been engaged in doing a detailed study of a slipped disc
surgery problem since the beginning of the new year. MRI and CT images
are to be used in conjunction with a package like ANALYZE. I believe
contour data and voxel data can be extracted. And the slice images in 16-bit
or 24-bit can also be extracted.
I'd like to first attempt to represent using what I read abt 3D textures
to represent in Performer the 'work' volume of the intervertebral area
in question. I hope this is a sensible and relatively quicker way to show
some results. There is no detail whatsoever for simulation.
Any direct answers on how this would be done inside Performer ?
What about introducing colour values to the images since MRI and CT data are
'colorless' ?
More importantly, has anybody tried representing inside the scene graph
a hierarchical structure of voxels and at the same time, this structure also
contains surface polygons of the anatomical objects such as bone and ligament
and spinal cord ?
I hope to receive some opinions.
We are also looking at the use of the PHANToM haptic device for interfacing
and providing finger tracking and eventually some force feedback.
Anybody has any comments ?
That is all for now.
Thank you for attention.
