I was using Paint Effect in Segment Editor and I noticed that the area that I painted on 1 slice also appears on the next two adjacent slices (if I try to erase this area on these two slices, it will also erase the painted area on the first slice too)
Expected behavior: Area painted on one slice will be only on that slice
Actual behavior: Area painted on one slice also appears on the next two adjacent slice
I appreciate any input on how to go about this issue, thank you!
@JoostJM also has a good point. If you selected a master volume and then switched, the geometry of the original master volume is used. In that case create a new segmentation and choose the volume with the geometry you want to have.
After checking the images again per your suggestions, I found that it may be because my master image thickness is 3 mm and the slice thickness at the viewing panel was at 1 mm. After I reset the thickness to 3 mm, the painted area stays within 1 slice. Thank you for helping me solve this!
