[Insight-users] register of MRI and a partial fMRI

[Yu Qi]

Hi Luis,
 
Thanks for your instruction.
 
I tried to set region to the fixed image by setting 
 start[2]=size[2]/2 and size[2]/=2 immediately after reading the image.
 
I use the Mattes MI metric and Centered Rigid 3D image transformation.
 
But every time I tried to run the .exe, it always told me there are too many samples outside the moving image. And I choose a smaller number for number of samples. I still got the same exception.
 
Why should this happen? 
It works well before I set the region.
 
Best Regards,
 
Yu Qi

Hi Yu,

Yes, you can use ITK for registering a fMRI to an MRI
even if they dont fully cover the same anatomical
regions.

You may want to use the MRI image as the Fixed image and
set the FixedImageRegion to the rectangular box that covers
the brain plus a border of about 10 millimeters. Take the
fMRI image as the Moving image.

You may want to use any of the MutualInformation Metrics
available in ITK.

For a full list of the Image Metrics please look at the
Groups in Doxygen:

Regards,


Luis
