<p><b>New page</b></p><div>== DTI Meeting Minutes | May 3, 2006 ==<br />
<br />
<br /> Present: Marty, CF, Gordon, Mark, Marc, Doug, KangUk, Sylvain, Marek<br />
<br />
<br />'''Scanning'''<br />
<br />
* Marek is continuing to test out the new sequence<br />
* New rule that a licensed MD must request MRI even if for research<br />
* Problem with reconstruction with multiple b-value images; causing FA to decrease significantly<br />
* At the scanner, unable to arbitrarily decide the number of baseline images; Marek will try to manually change whatever parameter this is<br />
* Can get resolution of scans down to 1.5x1.5x1.5, but this may increase noise in the images<br />
<br />
<br />'''Tensor Registration'''<br />
<br />
* Goal of this is coregistration of segmented white matter labelmaps with our data<br />
* In test of new tensor registration module from Mattan, linear registration is working better than nonlinear, which is way off<br />
* KangUk will test this with scans of the same resolution<br />
* This registration is done at scalar level, and is not actually using the tensors; we can try the same thing using AG and multiple scalar maps<br />
* Marc will try to troubleshoot this on Friday<br />
<br />
<br />'''Anterior Commissure, Mode/FA histograms'''<br />
<br />
* Gordon has sent scripts for creating AC boundary maps<br />
* Gordon has sent script for generating histograms; will continue to work on this using labelmaps PNL sends to him.</div>Andy
