[Insight-users] 3 image registration

[Niels Zelders]

Hello itk-users,

I would really appreciate some help in solving the following problem:
I'm trying to solve a multiple image registration problem and wondered 
if the ITK already contained some components for this.
To be more precise, I am trying to register a (fixed) 3D ultrasound 
image to a couple of (moving) 3D MR images. The MR images have the same 
domain, so it's not a general 3 image registration problem, but more 
like a scalar-image-to-double-valued -'vector'-image-problem. I do not 
know how to adapt the 'itkMattesMutualInformationMetric' (I prefer to 
use) in order to accept two moving images or a moving vector image 
(probably due to the fact that the neccesary 3D histogram construction 
is rather tricky to implement in a meaningful way??)
Does anyone know how to achieve this or have some hints on how to proceed?

Thanks in advance

Niels
