Good morning everyone! I’m looking for some help with Slicer. I’m working with someone who has provided me with a CT scan of a kidney with a tumor on it. My goal is to make an .stl 3D model of the kidney and the vasculature coming off of it, that will be 3D printed.
I’ve managed to learn the basics and use the volume rendering and crop model modules to make a very nice looking render.
I’ve also managed to learn how to use the editor for label mapping to create and save an .stl file of this. The problem I’m having is that my models always come out looking like this:
When you crop the volume, check Isotropic spacing checkbox to have cubic voxels and so avoid staircase artifacts. Then open Volume information section and make sure to have adjust Spacing scale parameter to have Cropped volume Dimensions values in the range of 200-500 (the higher the value is the finer details you can preserve in your model, but computation time and memory need will be increased).
