<P>=0A<BR>=0A Hi,<BR>=0A <BR>=0A&nbsp; &nbsp; &nbsp; I am working on MR-SPE=
CT Registratiom.My MR volume is in coronal orientationa and SPECT is in Axi=
al view. SO, I changed MR to Axial view using ITKOrientImageFilter and regi=
sterd Axial mr with axial spect image. I tried to initilize transform with =
centered transform initializer. But, I am getting runtime error.so,Used ide=
ntity transform as initial parameters for registration. <BR>=0AAfter regist=
ration and resampling image dimensions are changed to fixed image dimension=
s but, the final parameters are identity matrix.<BR>=0A<BR>=0AWhen i try wi=
th original mr and spect i.e with out converting 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 coronal view spect. Any more p=
rocessing is required to register coronal MR with coronal SPECt and Transve=
rse MR with Transverse SPECT. Can anybody tell me the reason.Because, Asfar=
as i know MR images will be in coroanl view. To register them with spect we=
 have to change them to transverse view as spect images will be in tranvers=
