Consultation request: subvolume to target volume registration methods

[amymmorton]

As part of the #99 implementation, Elastix reg was proposed for this application.. but I have been unsuccessful in completing our tasks:

Scene:

• 3DCT volume node 1 "neutral"

  • segmentation node of bones in neutral (radius, scaphoid, trapezium (rad | sca| tpm) etc)
  • using segmentation extra effects 'spit volume' extract subvolume node for each bone from neutral

• of the same hand, another 3DCT acquired in a different hand position "flexion"

• GOAL* 1) register each subvolume node to flexion and export rigid transformation

long term goal compile a sequence of other 3DCT , register subvolumes in series | 4DCT frames
