Hi guys!

I have cardiac CT images and I’m trying to segment the left ventricle cavity and left ventricle wall.

 ![Schermata 2021-12-17 alle 17.55.43](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/1/1/11537dbe0bb6edf22492d84116fb071e7924f80a.jpeg)

I have the edges of them differently colored (green for LV wall and yellow for LV cavity) and I need to fill them (I want green color between green and yellow edges and yellow color inside yellow edges). Is there anyway to do this?

Thank you
