Several series into one

Is it possible to combine several series of images into one?

When I choose one series the effect is unsatisfactory:

Reconstructing a high-resolution volume from 3 highly anisotropic volumes is a very hard problem. Actually, it is impossible to implement a general solution, because you need to generate missing information to fill in the gaps. However, there are solutions available for specific image types.
