<P>=0AHi All,<BR>=0A<BR>=0AI am working on MR-SPECT Registratiom.My MR volu=
me is in coronal orientationa and SPECT is in Axial view. SO, I changed MR =
to Axial view using ITKOrientImageFilter and registerd Axial mr with axial =
spect image. I tried to initilize transform with centered transform initial=
izer. But, I am getting runtime error.so,Used identity transform as initial=
 parameters for registration. After registration and resampling image dimen=
sions are changed to fixed image dimensions but, the final parameters are i=
dentity matrix.When i try with original mr and spect i.e with out convertin=
g mr to axial , Registration process is quite ok. I mean with out any erros=
 and matrix is not identity. But, Coronal view should be registered with <B=
R>=0Acoronal view spect. Any more processing is required to register corona=
l MR <BR>=0Awith coronal SPECt and Transverse MR with Transverse SPECT. Can=
 anybody tell me the reason.Because, Asfaras i know MR images will be in co=
roanl view. <BR>=0ATo register them with spect we have to change them to tr=
ansverse view as spect images will be in tranverse.<BR>=0A<BR>=0AThanking Y=
