Genearting 3D geometry from co-registration of angiography and intravascular imaging
 

Dear All,
I'm so new to this field. In fact I'm a interventional cardiologist and try to learn the CFD. I know it will take time. For this purpose I went to a training course for Fluid Dynamics design modeling, mesh generating and solving and post-processing. But for me the first big problem is to get 3D geometry. From the people within this forum, I wait your kind helps about getting 3D geometry before studying CFD. In our center we do coronary angiography from different projections and we do intravascular imaging with optical coherence tomography(OCT) that gives crossectional images and luminal contours of the stent implanted vessels. I read many publications about co-registration of 2 separate angiography image with intravascular imaging data to get 3D geometry, however could do up to now practically. My question is that which software should I use for getting 3D geometry? The angiographies are in dicom format( .dcm) and the OCT luminal contour data is in .ctr format, Could somebody help me about that issue please? Do we need to convert .ctr to . igs or stl format?
Best Regards

Dear drercardio,
I think there are software solutions available to convert dicom / .dcm-format to meshable 3D models. You may have a look at Mimics Innovation Suite (http://biomedical.materialise.com/me...ata-conversion) for example.
And as a first guess I really do think, that you need to convert your .ctr files to the more common .iges or .stl format.

If you have already decided for a CFD software package you might ask their support branch how to make your data readable for your CFD-software?

Best regards,
Holger
