Calculating cross section area

[Chandler, Kathy]

Hello

I have an image stack that represents a network of pores. I am using the analyze skeleton plugin to determine the lengths of branches in the pore network, but I'd also like to determine the distribution of cross-sectional areas along the length of the pore and in particular the smallest cross-sectional area in each branch. Having found that I'd then also like to know the actual circumference of that cross-section (bearing in mind that it is likely to be irregularly shaped rather than circular). Can anyone offer any advice on how to do this?

In addition, can anyone tell me how to calculate the volume of each branch in the network?

Many thanks

KC

Thanks for your suggestion, Bob. I took a look at the Thickness plugin, but not sure it will get me quite the answer I want. Unfortunately the pores are a complex shape and a sphere will not fit well. It also gives thickness rather than cross sectional area. I wondered if it was possible to take the skeleton (or medial axis) created by the Analyze Skeleton plug in and use it to determine the pore direction and therefore determine the angle that the cross section should be measured at?
