<DIV><FONT face=Arial size=2>Hi ITK expert, </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have two brain images that needs to be
registered. And their physical information are:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Fixed Image --</FONT></DIV>
<DIV><FONT face=Arial size=2> Origin = -116.800 -129.287
-53.4270</FONT></DIV>
<DIV><FONT face=Arial size=2> Spacing = 0.937500 0.937500
5.00000</FONT></DIV>
<DIV><FONT face=Arial size=2> Extent = 256 256 18</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Moving Image --</FONT></DIV>
<DIV>
<DIV><FONT face=Arial size=2> Origin = -148.048 -159.658
-99.7073</FONT></DIV>
<DIV><FONT face=Arial size=2> Spacing = 1.17188 1.17188
5.50000</FONT></DIV>
<DIV><FONT face=Arial size=2> Extent = 256 256 28</FONT></DIV></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The registration result doesn't seem
sensible..... Is it because the physical extent (in the z
direction) of the two images differ by too much?? Can someone
tell me if the physical size of the two volumes HAVE TO be close for
the regitration program to work properly??</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've get stucked by this question long
enough...Please specify for me the precondition on the input images of the ITK
registration program!! Thanx!</FONT></DIV>
