Dear experts
Just like the first picture, how to achieve this effect in slicer,
the cross-section of the model is displayed as a 2D image，not the pitcture 2

You can achieve this by:
- in Segment Editor, create a bone segment, use it to mask the volume, and also export it to a model
- show the masked volume with enabling thresholding in Volumes module
- optional: use Surface toolbox Decimate tool with 0.95 reduction (or 0.90 for higher quality) to make reslicing of the model faster
- hide the segmentation, show the decimated model, enable red slice clipping in Models module
