Identifying skull, brain, and tumors in MRI images
This project required identifying a target point for treatment, we used red to identify this tumor.
In addition, we wanted to avoid white matter in the brain during treatment, so we highlighted this in green.
Finally we identified the skull area in blue as an entry point for any surgical tools.
Creating 3D objects from 2D images
Using Slicer 3D and the compiled 2D MRI images, we were able to create 3D objects from the stacks of images.
White Matter Identification
Creating a 3D object representing white matter in the brain was a bit more involved. We used a precompiled library of DWI (or diffusion weighted imagery) and performed tensor estimation so that we could identify areas of the brain with increased water content (suggesting white matter and blood flow).
A Full Head
By overlaying all three objects, we had a model with:
skull identified in blue
white brain matter identified in green
and a tumor identified in red
Collision Detection with VTK
Using Visual Tool Kit software, we ran collision detection between the probe and white matter object. Notice the readouts in the bottom of the program reporting "White matter collisions"
