Hi there,
I have an animal brain's MRI with 3 volumes, each with a good resolution in one of the planes.
(i. 768x768x88, ii. 768x768x150, iii. 768x768x140)
As far as I understand freeSurfere doesn't have a 3D ihgh-res reconstruction tool, right?
My final goal is to get good tissue segmentation (pial-, grey-, and white-matter labels).
So now I am considering rescaling one of the scans in a high-dim. space (768x768x768) using imresize3 (or something similar for interpolation) with MATLAB.
The rescaling works, but the non-high-resolution planes turn out to be elongated. I am not sure how to get past this issue, and register the new rescale volume with one of the old ones (trying some params with mri_vol2vol might work?)
At the end I want to visualize rescaled 3D volume on top of the original scans, so I can at least (semi-automatically and then) manually segment it.
thanks in advance :)
