Oh, that is what “Scissors” effect do. I thought it’s for eraring.

It seems it’s not a filled rectangle. I found there is waring: Irregular volume geometry detected, but maximum error non-zero but is within tolerance (maximum error of 0.000576862 mm, tolerance threshold is 0.001 mm).  
I check [this post](https://discourse.slicer.org/t/question-regarding-irregular-volume-geometry-detected/8881). And set apply regualarization transform in the application setting, but still get this warning.

as you could see, the image is rotated a little. Any issue with the DICOM data?
