Operating system: macOS Catalina 10.15.7
Slicer version: 4.11 20200930
Expected behavior: I have very very carefully drawn the circumference of the aorta in green to be as precise as possible. When I click “show 3D” in segment editor, I expect to see 1 hollow aorta with a very precise radius.
Actual behavior: There is a smaller 3D aorta inside my aorta… I don’t understand… You can see in my images that the thickness of the aorta shell is literally a single pixel (as can be seen in the “frontal view on the bottom left”)… As I move my cursor to each side of the shell (again, as seen in the “frontal view” on the bottom left), we can clearly see that my cursor is passing through 2 different shells in the 3D view…
There is literally a smaller version of my aorta inside the bigger one… How is this possible? Can I get rid of it? Have I done a mistake?? 3DSlicer doesn’t seem to recognise that there are 2 aortas in either the frontal, saggital or axial view… It only sees this in 3D view…
Please watch my images in order to see how my cursor touches 2 aortas in 3D view when it is clearly only touching 1 aorta in the frontal view.
PS: I am using MRI images with a low resolution of 1.7 mm per pixel.
