3D CT Reconstruction

I've reconstructed a 3D skull model for animating human jaw movements.
See the MAJA Project .

Skull Dataset

Original data are 78 CT slice images each 512x512 at 65k greyscale.

Filtered data are 78 isosize PBM images, used for contour tracing.

Contour file can be processed with NUAGES a 3D reconstruction package.

~13000 triangles
and ~7000 vertices

I wrote two tools for CT image conversion:

CT2PGM , for filtering and cropping CT images.

PBM2CNT , for contour tracing of B/W bitmap images.

Look again on this page to get more information, sample pictures and programm updates.
