  • re: State of the art in CT/MRI to FEM

    Dear Biomch-l Readers,

    Several months ago I posted a query concerning processing CT (or MRI) data
    into FEA usable forms. Since then, there have been at least two other postings
    concerning the same topic. Here is a compilation of what I have found out
    from other Biomch-l readers:

    >From John Steege:
    We use EXTRACT / IBID from Cornell. It works
    well and is available at low cost (with source) to universities.

    (the place you'll actually order the software from)

    Good luck.

    Several readers suggested contacting CEMAX:

    CEMAX offers a software
    package that reads archive tapes of several CT manufacturers
    (also can provide digital connection and translation from
    some CT scanners) and display 2D and 3D images from those
    images. We do indeed create a geometry but it is a volume
    based geometry NOT a surface geometry (like with triangles
    or surface patches). We have an open data base and describe
    the format of our files to all so it is very possible to
    do further processing on the data. We do have a "display only"
    surface description for fast display. It is a list of points
    on the surface with a 3D gradient attached to each point.
    There is no connectivity between points.

    The contact at CEMAX is:
    Linda Fellingham

    Several readers suggested MOVIE.BYU from the University of Utah.
    There were also several people who suggested contacting researchers who have
    developed their own specific code:

    David Dean wrote:
    There is also a group at Cornell University's Dept. of Mech. & Aerospace
    Engineering led by Dean Taylor and Don Bartell. They have been marketing
    a package that constructs 3D CT isosurfaces and can output the data to PATRAN
    format. I have not been in touch with them in several years but I think
    Dr. Taylor's number is: (607) 255-3575.

    As Dr. Ateshian posted a few weeks ago, there seems to be no public
    domain code (or commercial for that matter) available specifically to
    convert CT/MRI image data into a from directly usable by FEA packages
    and or preprocessors such as PATRAN. We are writing our own code that
    will be universal enough to process the image data into a form directly
    usable by FEA codes. We are just starting so I don't have any progress
    information yet. If anyone is interested in collaborating, send me an
    email message or give me a call.

    Sorry for the delayed summary posting.
