Use Volume Fusion to merge images together that can't be merged using the Tile Sorter.

Registering the volumes for fusion using landmarks:

• Add landmarks using markers to match specific pixels in both volumes.
• You need 3 landmarks at a minimum, adding more is usually not necessary.
• Add the landmarks always in the same order. This makes fusing the volumes much easier.

Registering the volumes for fusion by using surface transformation:

• Extract an isosurface from the moving volume to use as a reference
• Copy the surface over to the base volume and use the surface transformation tool to work out the translation, rotation, and scaling required (most easily done in VR)
• Copy the transformation parameters into the Volume Fusion tool

Fused volumes can either merge equivalent channels or combine the volumes as different channels.

Volume Fusion maintains the resolution of the Base volume and matches that of the Moving volume. Take care when merging volumes of vastly different resolutions.
