> For the big image, I know its size and also the coordinates in mm of its

> For the small image, I know its size, the coordinates in mm of its first
> voxel with respect to the same frame of reference and also the 3 euler
> angles (phi, theta, psi) that defines its orientation.
> With that, how can I compute the transformation matrix that will allow
