Model to Model Distance in tubular structure - Intestin wall

Support

Dear Slicer Community,

I am working on a heat map representation of the thickness of colon wall in mice. I Segmented the lumen, the colon wall and the area outside the outer colon wall, and exported the segments to models. Using Model To Model Distance module I got the distance map in a VTK Output File. In the Model to Model Distance module I am using the lumen as Source and the “outside area” as target. The VTK output than has the distance information and a shape of the source model. But I want to show this information on the colon wall. Is it possible to transfer the color coding (I mean the thickness coding) to the model of the colon wall?
The pixel size is too big for the segmentation of the outer and inner surface of the colon wall.

Thank you for your help.

Just seeing this in a rush, a quick idea: can’t you just swap the inputs? Then the reference will be the higher quality colon wall

Thank you Csaba!
Unfortunately no, the colon wall is actually the “gap” between the 2 models… :slight_smile:

Well, transferring the coloring is not possible, at least far from straightforward. How about calculating the difference of the two models you are interested in from the colon model, and combine (e.g. average) the two scalar arrays that you can show in the model of interest?
