Regarding calculation of geometric indices

[MUDRIKA SINGHAL]

Hello!

Can anyone please tell whether SimVascular facilitates the calculation of geometrical parameters such as curvature, torsion and tortuosity from the 3D constructed model?

Thanks!

Regards,

Hi Mudrika,

SV does not explicitly compute the geometric quantities you mentioned. However, the centerline geometry computed in the SV Modeling Tool and ROM Tool has data (e.g., MaximumInscribedSphereRadius, CenterlineSectionNormal) that can be used to compute these quantities. You could also just use the centerline coordinates directly, like fitting a spline to a section of the centerlines.

The easiest thing to do would be to write a Python script to read a centerlines VTP file and extract the data for the computations. See https://github.com/ktbolt/cardiovascula ... results.py for example about how to read this data.

Cheers,
Dave

Thanks David, I will check this out!
