I am a Student of M Tech (CFD) and working on Nasal Airflow simulation. I want to prepare a 3D geometric reconstruction of Nasal cavity. The computer tomographic (CT) images are used to obtain 3D model, but I dont know how ? Can anybody help me by explaining how these images are processed to get 3D model and is there any software used in medical technology to convert into 3D model ?
This is my guess am not sure how this works. I you can import CT images to any of the modelling packages like CATIA etc, you can import do some repair and get the things done or look at the file format of the CT Image and then reconvert it to known formats used by regular packages.
The first step is segmentation and edge detecting using MATLAB, the second step is reconstruction 3D using MATLAB fonction or CAD soft.
Hi,
I think I have an answer for you! 3D animation program Blender can help you to prepare the nasal cavity, the air and the simulation of it. It is a free software which is worth thousands of dollars.
Check the links in the following order:

Good luck!

If anyone is still looking for a solution to this issue, my commercial software program Simpleware can help in reconstructing and meshing complex CT data of this type for visualisation, inspection and export for simulation. Please see http://simpleware.com/ for more information.
