Hello, I’m working on a human fetal head stained with Phosphotungstic acid (PTA) to be able to visualize soft tissue.
I’ve used the scissors tool to erase all unwanted surroundings of the tongue, yet after fixing the threshold it still includes most of the mandible and muscles around it as they all share the same intensity range even after trying to increase or decrease the contrast.
After trying to refine the boundaries of the tongue as much as possible still, the root of the tongue slices aren’t as clear as the dorsum (superior border)
I’ve also tried the “Grow from seeds” tool but this is the result I get after many attempts
with and without changing the Window/Level in the Volumes module.
In my opinion, the main problem is finding the correct threshold that is confined to the area selected, even though one of the windows/levels show excellent differentiation between the tongue and its surroundings as shown below:
I would still get the same results (a lot of noise/unwanted slices around the segmented area)
Help is needed to overcome these issues…
