Hi, <div><br></div><div>This might be a vaguely defined question. Here is my situation. </div><div><br></div><div>I used the example 8 of deformable registration (3D bspline) to register A and B images. I subsequently obtained a vector field and an output image. The output looked exactly like the reference image which is excellent. </div>
<div><br></div><div>I displayed the field on Matlab. It looked fine. I therefore apply the vector field to deform my image in Matlab. </div><div><br></div><div>However, the moving image couldn't deform back to the reference using the same vector field. During the process of opening the data in Matlab, either the orientation and values of vector field must have changed. I wonder if anybody knows how this change might occur. </div>
<div><br></div><div>Thanks,</div><div>Stephen </div><div><br></div><div><br></div>
