I have 3 volumes:  
SAG OK  
AXIAL OK  
COR OK

Each one is a complete volume, but they have a better resolution only in one direction. When i render each one a full skull i shown but with awefull resolution  
I need to pick the Sagital part from SAG OK, the Axial part from AXIAL OK and the Coronal part from COR OK to create a new volume. How can i do it?

Thanks!

This is a common question, but unfortunately there is no readily available tool or approach you could use to easily combine these three volumes into a single “super-resolution” volume.

See earlier related post here: [Combining volumes - what am I missing?](https://discourse.slicer.org/t/combining-volumes-what-am-i-missing/2941)

A quick idea that others who are more experienced in such matters will hopefully comment:

- Create a volume that has the highest resolution in each axis
- Fill in the slices from the other volumes in the proper planes
- Use a [fill holes filter](https://github.com/PlusToolkit/PlusLib/blob/master/src/PlusVolumeReconstruction/vtkPlusFillHolesInVolume.h) to interpolate the empty areas (the boxes between the slices)
- Downsample as needed

I agree with @cpinter, there are definitely things you can do to explore. But the key issue with any of the approaches to combining those volumes into a single one will be that you will either lose the resolution (or blur your data) that you have in-plane for the individual source volumes, or you will have inconsistent resolution in different locations of the super-resolution image.

You can check out this survey for the intro to the topic (I didn’t read it, but I trust the authors did a good job surveying the field): [https://link.springer.com/article/10.1007/s00138-014-0623-4](https://link.springer.com/article/10.1007/s00138-014-0623-4). As the authors point out from the outset, “superresolution […] has been a very attractive research topic over the last two decades”, which says something on its own…
