<DIV><FONT face=Arial size=2>Hello All:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I will like some advice concerning two issues about
non-rigid registration:</FONT></DIV>
<DIV><FONT face=Arial size=2>1) I am using DeformableRegistration to register
two 3D images (data sets of human vertebrae). After I made the
necessary accommodation for 3D to the parameterlist and the code, I ran the
DeformableRegistration1, I checked for the correctness of the
vectordeformationfield scalar components by extracting them and analyzing
their values. However, when I use the Warperfilter and the
vectordeformationfield to get back to a scalar image I get a image of the right
size but it is all zeros. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>2) I am trying to non-rigidly register two image
data set of human vertebrae (I am interested in having a displacement field that
gives me correspondence between the surfaces (edges, contours...) of both
vertebrae, I am not really interested in the information inside the
vertebrae--), should I use another filter, like affine or B
spline....</FONT></DIV>

<DIV><FONT face=Arial size=2>Thanks for you advice, Barbara</FONT></DIV>
