Dear
Dear Biomch-list readers,
ALmost two months ago I asked to the Biomech-list how to deal with CT and
MRI images. I wanted to post all the answers and thank all the people that
help me (sorry for the delay):
My question was:
>I am working in a three dimensional model of the knee, and I am trying to
>reproduce the geometry. I have connections with a Medical Center that
>has a very good equipment in Computarize Tomography and Magnetic
>Resonance. Does anyone knows how to convert the data of a Picker machine
>in a legible format.
>
The answes:
1.
>Carmen,
>A good place to start with reading Medical Image files is David
>Clunie's Medical Image Format FAQ
>http://www.rahul.net/dclunie/medical-image-faq/html/
>For making models from the data, start with the NASA 3D
>reconstruction reference page
>http://biocomp.arc.nasa.gov/3dreconstruction/refs/
>For volumetric visualisation, try
>http://topaz.sensor.com/work/ref/medicine/medical-volume-vis-faq/
