4D Flow MRI inlet BC

Hello
I wanted to find out if SimVascular is able to handle 4D flow MR based flow fields as inlet BCs, as against one of the standard inlet BCs that SimVasc converts the flow waveforms to?
Thanks
Tejas

Hi Tejas,
SimVascular is not currently able to extract flow fields as inlet BCs from 4D flow MR.
But interesting enough the SimVascular team was discussing this very thing today so I think that it will be added, not sure when though.
Cheers,
Dave

I'm interested in this topic.
I need to know software (in particularly free software) that allows me to obtain a flow field from 4D Flow MRI sequences.
Have you some suggestions about it?
Thank you

Hi Luca,
I believe that the Crimson software package (
http://www.crimson.software/features.ht ... w_profiles) has this functionality, they just published a paper about the method they use (
https://ieeexplore.ieee.org/document/8572777).
If you would rather use SimVascular for your modeling then it might be possible to provide this functionality using its Python interface.
Cheers,
Dave
