3D image registration for CT to Laser

Hello everyone
I am looking for a way to perform matlab based 3D surface registration method to match a CT scan to the 3D Laser scan.
We have Ct scans of the patient knee and we have a 3D laser scanner with the help of which we take 3D Laser scans of the same knee inra-operatively for checking implant placement. Now my question was is there a way to 3D register a CT scan and a Laser scan in Matlab. I found couple of toolboxes but I am bit confused. Your advice is much appreciated.
Thanks Jolanta.

There are no 3D registration functions in MATLAB, currently. The only stock registration function offered is IMREGISTER, which is for 2D-2D intensity-based registration only. If you want to do this in MATLAB, you will end up coding most of it yourself, though certain toolbox functions like imtransform() might be useful building blocks for you.
You could also search the File Exchage for relevant tools. For example, this might be appliable if you can segment the surface you want in the CT image
Any reason not to use ITK or something else more dedicated to registration?

No - you could use expensive but extremely powerful standalone programs like Avizo that were build for volume visualization, registration, and measurements. They can do things MATLAB can only dream of.

imregister/imregtform were enhanced to support volumetric registration a few releases ago, for anyone just now coming to this thread.

Yes, imregister and imregtform will perform 3-D registration when given 3-D inputs.

please give some help on how to perform 3d volume registration using imregister without using RIRE
