[Mristudio-users] Question about Coregistration between high-resolution anatomy and DTI data

[Castaneda, Salvador]

Hello SC,
 
I think i have already had this question and there is a way to
coregister with an anatomical reference. you can probably read Dr.
Mori's answers in earlier threads if you keep the emails.
What i have done but didn't continue to use it, was to reduce the size
of the anatomical image to the size of the DT image using diffeomap.
Later did AIR in DTIstudio using the anatomy as a reference to the
Mosaic DTI images i had, which were cut in the same size as my anatomy.
After this coregistration there was a nice mixed image of anatomy with
the DTI. So then i saved this as separate analize file and proceeded to
the DTI analysis as usual. When it came time to draw my ROIs, I would
open the coregistered anatomy with DTI analize file, which know was
exactly the same position and size, and then i would have nice clear
ROIs. The ROIs i would draw either with ROI editor or DTIstudio.
I didn't continue to do this, because it is obviously tedious method. So
i proceeded to do all the DTI analysis in DTi studio, export the files
as Analize, and then coregister my anatomy images with another program.
It was hard for me to work with ROI editor because the resolution of my
DTI is relatively bad. So i had to use a different program. 
Any way i hope this helps,
 
cheers
Salvador C

I know DTI studio supports only intra-subject/intra-DTI registration.
I tried to use Diffeomap, but it complained about images are not of the
same image parameters.
If you have a complete guide about how to coregistration of DTI (e.g.
256x256) to High-resolution anatomy (e.g. 512x512), could you share it
with me and whole community?

I appreciate that in advance.

SC
