View Full Version : finite element modelling of bone

Is there anyone out there who has developed a reliable and "quick" procedure
for developing finite element meshes of human bone from CT? In order
to use commercially available software, I need several questions answered:

1) An edge detection needs to be applied to the bone in order
to define the outer contour. Has anyone developed a method
that automatically applies an edge detection and outputs a format
acceptable to convential FEM programs?

2) The material property of bone is quite variable. Has anyone developed
a script or program to take CT attenuation and convert it to the modulus on
a mesh element?

I am currently using user-interactive programs which achieve these goals,
however, it is a very time-consuming process. Any suggestions?

Thank you for your help,
