This kind of reconstructions are good for humans to review but not well suited for 3D reconstruction. See this post for more details:

> In general, these multiple low-resolution acquisitions are not well suited for any 3D processing, so the best would be to acquire proper 3D volume, with as isotropic spacing (cubic voxel shape) as possible. You may try to find toolkits that can create an isotropic super-resolution image from multiple low-resolution sweeps, but this is a difficult image reconstruction problem, so there are no standard solutions. Have a look at this post [Import volume by projections](https://discourse.slicer.org/t/import-volume-by-projections/2871/6) for info on a toolkit that mig…

CBCT volumes are usually reconstructed as a single isotropic volume (same spacing value along all axes). The software that created the reconstructions should have an option to create a single high-resolution reconstruction.
