Operating system: Windows 10
Slicer version: 4.8.0
I’m trying to make a bone model from MRI data using slicer. The idea is to colour each slice and then slicer constructs a 3d model. I’m quite new to the program. I’ve bought a trackpad and am coloring in the parts which I think are bone in the image but the resolution is not very high so I’ve not been able to come up with a more efficient method.
Kind regards

In general, bone is not very well visible in MRI. If you have the option, use CT images instead.
You can find step-by-step segmentation tutorials here: [https://www.slicer.org/wiki/Documentation/Nightly/Training#Slicer4\_Image\_Segmentation](https://www.slicer.org/wiki/Documentation/Nightly/Training#Slicer4_Image_Segmentation)

Have you managed to find a solution to this? I am interested automating the segmentation of bone with MRI.

@Sezen I have published a paper where we accurately and automatically segment the skull and mandible from MRI using CT bone as training labels. If you have both CT and MRI available from a group of patients, you could try something similar as our method: [Towards MRI-Only Mandibular Resection Planning: CT-like Bone Segmentation from Routine T1 MRI Images Using Deep Learning](https://www-mdpi-com.proxy-ub.rug.nl/1943-3883/18/3/40)
