Our research group at the Veterinary Orthopedic Reseach Laboratory at UC
Davis is investigating the use of helical computed tomography images in a
study of the knematics, morphometry, and biomechanics of the elbow joint.
We would like to develop a Cartesian coordinate system that can be applied
consistantly to the elbow joint of every specimen or patient. The purpose
is for the subsequent comparison of measurments between samples or patients.

We have not been able to find a reference to this this type of system in
any joint or guidance as to how Cartesian coordinate systems should be set
up in biological specimens with three dimensional images.

Is anyone aware of references or previous research using this type of
system? Any help is greatly appreciated.

Thank you
Kurt Schulz
