I think the best way is to turn on interpolation (depending on manufacturers, they call it differently, but technically called "zerofilling" or "zeropadding", which make the matrix size twice as large) would be the best way, although you can't do it after scans are done.<div>

This will not only adjust the brain image matrix to 1x1x1 (181x217x181), your manual ROI drawing could be more consistent.<br>

Hello,<br>
<br>
<br>
I have a quick question regarding the zoom feature. Is there any way to make DTI studio allow me to zoom in more? My image dimensions are 128x128 with a FOV of 256x256 and 2x2x2 voxels. When I zoom in to the max amount allowed by DTIstudio (2 clicks of the + icon), the image is still relatively small for ROI drawing. Can I play with the image parameters or anything else to increase the amount that I can zoom, or am I stuck with this view?<br>
<br>
<br>
Thanks alot!<br>
Matt<br>
