Resize ROI to same image size


I am in the process of making a head CT template, there is one thing I would like to do with Slicer, though I am not sure it’s even possible. The CT scan has a size of 512x512, I would like to apply a linear scaling so that the brain volume occupies a larger portion of the original image. I can manually decide which portion of the image is interesting.
I was not able to find the solution in the transform module, is it possible ?


You can use “Crop volume” module to choose an arbitrary portion of a volume and resample it at any resolution you choose.
