<br>
I have several MRI volumes of the same anatomy, which have been<br>
spatially aligned. These volumes have been acquired using different<br>
(orthogonal) acquisition direction, so they have thick slices, but in<br>
orthogonal planes with respect to each other. I would like to<br>
construct one volume, which would essentially combine the input<br>
volumes, interpolate over the multiple input volumes to produce an<br>
image of better resolution.<br>
<br>
Is there something in ITK that could be used to help me in solving<br>
this problem? It seems I need to do some sort of weighted averaging<br>
over the neighboring voxels from the input volumes. Can anyone suggest<br>
how to approach this problem?<br>
<br>
Thanks<br>
