<DIV><FONT face=Arial size=2>Hi George, </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanx for your reply. What makes my
program a bit challenging is the fact that I am trying to register two volumes
of different types (one is T1 weighted image and the other is diffusion
weighted image). They have different physical dimensions, different number
of slices, and the way the data looks is quite different too. My
ITK program used to work for the volumes of the same time, but now I try to
run it with two volumes of different types, it gives me segamentation
fault. Do you know why?</FONT></DIV>

[Insight-users] register two volumes of different types<BR><BR></FONT></DIV>
<DIV><FONT face=Arial size=2>Hi there, Good day!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have two 3D image data I want to
register. The movement in the data is 3D rigid. So, I use
<FONT size=2>VersorRigid3DTransform. The two volumes are
different types of image data (one is T1 image, and the other
is diffusion weighted image), so I use <FONT
size=2>MattesMutualInformationImageToImageMetric.</FONT></FONT> I know
ITK can register two volumes of different physical dimension. But
doesn't it also register two volumes that have different number of
slices? My program doesn't work for two volumes of different types, am
I missing something?</FONT></DIV>
