Is it possible to change a cbct to a 2d Radiography sagital for orthodontics [image] Thanks

Yes, you can generate a 2D x-ray image by volume rendering module: disable shading, use a liner ramp-shape opacity transfer function (maximum opacity around 0.1 or lower), plain white color map, and set the 3D view background to black. Volume rendering with a default bone preset: [image] Volume …

I wonder if adding a “X-ray” volume rendering preset would be helpful ? Ideally, switching to this preset would also change the background to black but I am not sure it is the right place to do this.

I think it would be nice to have. Maybe in a separate module? I have basically written the same thing that generates DRRs using different methods. I have found it helpful in presenting the information to clinicians in a way that they are used to visualizing from standard practice.

I’m not sure a transfer function can represent an X-Ray. I think you need a digitally reconstructed radiograph. The is an ITK example that implements the DRR . Also, as part of a DARPA-Sponsored Virtual Autopsy Project we generated hundreds of DRR’s of soldiers. I could probably resurrect the ITK c…

I’ve added an X-ray VR preset - see pull request here: qSlicerTractographyFiducialSeedingModuleTest1 failure · Issue #1209 · Slicer/Slicer · GitHub
