This likely isn't trivial because the images will look quite different and may be of different resolutions, etc. I suspect you'll be lucky to find code that works "out of the box." As I see it, you have two options. Firstly, find a research group who has done this (look on PubMed) and contact them. If that fails, start learning some image registration tools. Two that would help are: http://www.nitrc.org/projects/cmtk http://elastix.isi.uu.nl/

You can also look the MATLAB tools: http://www.mathworks.co.uk/help/images/ref/imregister.html (now supports 3D registration) http://www.mathworks.com/matlabcentral/fileexchange/20057-b-spline-grid-image-and-point-based-registration
