[ITK-users] How to use rotation matrix and translation to perform Rigid 3D transform?

[paniwani]

I have been able to use a 3rd party radiotherapy visualization tool to verify
that the registration works properly. So I don't think the images are
registered to a particular tracker. That should not be a problem.

The Euler transform states:

"The serialization of the optimizable parameters is an array of 6 elements.
The first 3 represents three euler angle of rotation respectively about the
X, Y and Z axis. The last 3 parameters defines the translation in each
dimension."

I don't have Euler angles; I only have a rotation matrix M as above. Can I
just use the Rigid3DTransform (as I seem to already have all the input
parameters for it and won't require any conversions)?
