[Mristudio-users] Image proportions mismatch

[Dorian P.]

Dear all,

I have two images acquired at slightly different FOV on the same subject. I
open them with DTIstudio and the proportions are not good. Looks like one
is shrinking too much:

*The settings I used to open **the left image are:*

[image: Immagine in linea 2]
Parameters from scanner
.    Max. number of slices/locations    :   70
.    Scan resolution  (x, y)            :   128  126
.    FOV (ap,fh,rl) [mm]                :   256.000  140.000  256.000



*And here for the right:*

[image: Immagine in linea 3]
Parameters from scanner
 .    Max. number of slices/locations    :   66
.    Scan resolution  (x, y)            :   112  112
.    FOV (ap,fh,rl) [mm]                :   228.571  132.000  256.000

Both images have a final resolution of 128x128, confirmed by the "recon
resolution (x y)" parameter in the PAR file.

Any idea why the proportions do not correspond in DTIstudio? They are
correct only if I set FOV 256x256 for both.

Thank you.
Dorian

P.s. If you can't see the images I can send them through a dropbox.
