Dear all,

I am looking for some online CBCT scan datasets for my project. Mainly, I am interested in datasets of human jaws including teeth and jawbones. Could you please let me know if there are any available datasets that I can use in my research?

Best

I can give you [my own](https://www.dropbox.com/s/kt3mhbyrpn4w2km/DZ_CBCT.nrrd?dl=0), which is a start. I am not aware of an online repository, but @bpaniagua might be.

@dzenanz This is a very nice quality CBCT. Would you like to contribute it to the Slicer sample data sets?

Yes, how do I do that? If you can add it, you have my permission to do so.

This is not in the latest nightly’s `Sample Data` module. Did you add it, and where?

There is also an accompanying [MRI](https://www.dropbox.com/s/xe2x8z1ds1uhcb9/tmj_DZ.nrrd?dl=0) taken a few weeks after the CBCT. The pair is probably more interesting then CBCT alone.

I also manually created a rigid [transform](https://www.dropbox.com/s/l6vm1bpcspz57nl/dz_CBCT_to_MRI.tfm?dl=0) to register them:

@dzenanz Thanks for shating the additional image and transform. The data set is now added to Sample Data module as “CBCT-MR Head”:

I downloaded the latest nightly, and I didn’t notice it at first. I found it by looking at your screenshot. The reason: thumbnail is missing from it.

 ![Screenshot 2021-09-16 09.37.38](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/8/2/821903c488e4fbca3c7b2ed3783ab1846653a5fe.png)  
Am I the only one with this symptom?

**Edit:** the data is downloaded properly once the button is clicked.

Thank you, I’ve fixed the thumbnail now.
