<DIV> </DIV>
<DIV>I want to do registeration of two image volumes ... </DIV>
<DIV> </DIV>
<DIV>each of them have different spacing but the same dimension and voxel type. </DIV>
<DIV> </DIV>
<DIV>Also both of them are from the same modality.</DIV>
<DIV> </DIV>
<DIV>But i want the registration to use only the following set of transformations:</DIV>
<DIV> </DIV>
<DIV>>>> Translation along x,y,z axis</DIV>
<DIV> </DIV>
<DIV>>>> Rotation along z-axis onlye</DIV>
<DIV> </DIV>
<DIV>>>> Anisotropic scaling along x,y,z.</DIV>
<DIV> </DIV>
<DIV>None of the transforms available seem to allow me to implement this combination. </DIV>
<DIV> </DIV>
<DIV>>>> AffineTransform includes shearing which i dont want. </DIV>
<DIV> </DIV>
<DIV>>>> Similarity3DTransform implements homogenous scaling, but i want anisotropic scaling.</DIV>
<DIV> </DIV>
<DIV>Also i dont know how to restrict the rotations to happen around the z-axis only.</DIV>
<DIV> </DIV>
<DIV>Is this possible with one of the existing transform classes or do i have to write a custom transform class ??? </DIV>
<DIV> </DIV>
<DIV>Please Help !!!!!!</DIV>
<DIV> </DIV>
<DIV>Thanks in advance !!!!!</DIV>

<DIV>Eagerly waiting for your reply !!!</DIV>
