Would be interesting but can't say.

What you can do is get hold of some online CT data, import it into OsiriX or a similar DICOM reader. Then export the volume rendered scan as a STL file. That'll give you a very rough file, but it's a starting point. Another method is to import the CT DICOM files into Slicer, it's a free an open source app that let's you fine tune the part of the CT image series that you want to convert to a 3D STL file. You'll still need to refine and simplify the STL file in Solidworks before you can mesh it in Ansys.
