Painting on oblique images

v5.8.1

sample data cta abdomen.

Create double oblique…

I have never understood this.

When I click with the paint tool, I do not get a circle.

I might understand this.

But I definitely do not understand why when i drag the circle around, it fills in?

Same behavior with and without masking.

Thanks for the reply.

I was aware of this. I’m not sure that it is the exact same issue. It may be. This has always confused me.

I do not understand why when one clicks, there is one segmentation, but when one drags additional pixels are segmented.

I’ve been struggling with this issue for some time. My work around was to drag the roi until it is complete. So I am really iteratively painting away the “artifacts” without reslicing.
