[Mristudio-users] Coregistration using AIR

[Shigetoshi TAKAYA]

Hello


I have two scans of DWI with time interval for each patient (1st scan and 
2nd scan). I would like to coregister the images in the 2nd scan onto those 
in the 1st scan in each subject using Automatic Image Registration (AIR) 
algorithm implemented in DTIStudio, for the purpose of drawing ROIs in the 
same brain regions in both scans.



First, I did eddy current correction and motion correction using affine 
transformation in each scan (1st scan and 2nd scan).

Then, I coregistered the B0 image in the 2nd scan onto that in the 1st scan. 
And I would like to adjust the same transformation matrix to the rest of the 
images in the 2nd scan.



I know that the transformation matrix can be saved when conducting AIR. Can 
we use this file to transform the rest of the images in the 2nd scan?



Many thanks,



Shigetoshi Takaya
