<div>Hi everyone,</div>
<div> </div>
<div>I've been using some of the motion correction algorithms for some time with contrast enhanced breast MRI cases. I'm specifically using registration example 6 from build 2.0.0 (BSplineDeformableTransform) as an example. For most cases it works very well. Every so often I do get some strange results. I have included three links with small pictures showing the results of registration of one image:
</div>
<div> </div>
<div>The stationary image:</div>
<div><a href="http://www.mark-w.com/stationary.jpg">http://www.mark-w.com/stationary.jpg</a></div>
<div> </div>
<div>The moving image:</div>
<div><a href="http://www.mark-w.com/moving.jpg">http://www.mark-w.com/moving.jpg</a></div>
<div> </div>
<div>The result after registration:</div>
<div><a href="http://www.mark-w.com/registered.jpg">http://www.mark-w.com/registered.jpg</a></div>
<div> </div>
<div>I'm just wondering what could cause such a distorted result. Is it a characteristic of the image itself that causes this? Is the change in contrast from stationary to moving image so great that it's really getting thrown off pretty badly? Is there a way I can limit the search space for registration, so that the algorithm knows not to stretch the image so far?
</div>

<div>Thanks for any info,</div>
