[Mristudio-users] combining over DTI scans

[susumu]

If I understood your question correctly, you want to combine two DTI
datasets with different b-table. For example one 30-orientation and one
15-orientation.

 

You can load the 30-orientation data and 15-orientation data into one
window. First open the 30-orientation using the "open" icon at the top left
menu and then get a new viewing window. Then open the 15-orientation using
another "open" icon at the right column of the viewing window. In this way,
you get all 45 + b0s into one window. Then you can save all into one file
using the "save" icon in the right column. In this way, you can create a
concatenated file in which you have b0+30DWIs+b0+15DWIs.

 

Next, combine the two b-table to create a 45-orientation file. Make sure
that the order of the b-table is the same as the order of the stored images.

 

In this way, you can combine the two.

Hello all,

 

I was wondering if you could suggest how to combine different DTI scans,
each with a seperate gradient table, in DTI studio. Basically, I have two
DTI scans and I have two sets of gradient tables for each scan (gradient
table for each scan corrected separately for angulations and motion
correction using the DTI gradient table creator code written by Johnathan
Farrell). Next I want to use these separate gradient tables for each scan
for further analyses. Can this be done using the dpf format?

 

Thanks in advance,

Mayuresh.
