Dear users  
I am attending to calculate the volume of nasopalatine canal but didn’t find the way. I tried to use the usual steps of segmentation process commonly used for hard/bony structures but failed to get my point.  
Any suggestions or guidance will be appreciated.  
Thanks in advance  
I attached an example for the required work.
