I am working on a project where we are segmenting lesions from an MRI using the paint tool from the Segment Editor module. We are using a large brush size along with a threshold so only pixels within a certain range are included in the segmentation.
My problem is that I want the segmentation to be only in 2d (i.e. just affecting the pixels on the current slice of the volume). For example, if I do a threshold paint on slice 10 of the MRI, I don’t want it to paint any of the pixels on slice 9 or 11.
I figured there would be a way to disable this, but I can’t seem to find the option.
I am using the following version of slicer: 4.9.0-2017-11-10 r26630
