I’m trying to calculate the diameter of a vessel (segmented from DICOM) at any desired point in the model.

I have used VMTK Extract Centreline to plot a centreline with \>200 points to allow for selection of the desired location in the model however I cannot calculate the distance from the centreline point to the boundary of the model/segmentation.

Using the centreline quantification gives only the values of entire branches
