Hello,
I`m a postgraduate student and I`m doing a research about effect of orthognathic surgery on pharyngeal airway space. I have 3D models in different times of pharyngeal airway space saved in *.vtk file and i need to calculate the minimum cross-sectional area of these models. Can someone please help me, how to easily measure this cross-sectional area and how to use software SPHARM on this project? What setting should I use and where can I find the result? 
Thank you for your help. 
Best Regards
Ondřej Masák

Hi,
can someone please clarify me, how to use Spharm exactly like in this article? Im little bit confuse.
Can someone please give me some instrustions?

Hi Ondrej,


Thank you for your interest in SPHARM.
I suggest that you get started by trying SPHARM-PDM using the example data provided in the documentation section, following the steps indicated in the tutorial. The tutorial provides information on how to compute the cross-sectional area measure we used in the paper you attached.

Example data: https://www.nitrc.org/docman/view.php/308/1981/SPHARM_Tutorial_Data_July2015.zip

I hope this helps.
