1. How to extract the Circle of wiilis geometry from CT DICOM data, which segementation technique can be used?
2. Can we directly import the ansys mesh file (defined inlet and outlet) for simulation in Simvascular?

Hello,

1. How to extract the Circle of wiilis geometry from CT DICOM data, which segmentation technique can be used?


The segmentation technique you use depends on the quality of the imaging data. You can use level set for high contrast data.

2. Can we directly import the ansys mesh file (defined inlet and outlet) for simulation in Simvascular?

SV does not support reading in Ansys mesh files. You will need to convert the files into VTK files with the format expected by SV.

Cheers,
Dave
