<p><b>New page</b></p><div>== DTI Meeting Minutes | May 10, 2006 ==<br />
<br />
<br /> Present: CF, Marty, Marc, Mark, Toshiro, KangUk, Doug, Sylvain, Gordon<br />
<br />
<br />'''New Sequence:'''<br />
<br />
* Nan-kuei will be helping with testing of the new sequence<br />
* Once sequence is decided, planning on bringing in all previous DTI subjects during month of July<br />
* Test images<br />
** 1.7^3 resolution<br />
** Problem with a missing DWI for one slice--causes major differences in tensor estimation<br />
** Strange cross-section artifact superimposed on DWI images (doesn't seem to affect FA maps as much)<br />
** Forebrain appears dimmer than hindbrain<br />
** Gordon will discuss these issues with Marek and Nan-Kuei<br />
<br />
<br />'''KangUk - White matter atlas coregistration:'''<br />
<br />
* Both linear and nonlinear coregistration still not that great for a problematic case<br />
* KangUk will test on a better case; will try to do dual-channel coregistration in AG using FA and Mode<br />
* Will continue to use scalar maps for coregistration; using structural would add an additional registration step and more error<br />
<br />
<br />'''DTMRI scalar testing:'''<br />
<br />
* Needs to be an estimation error map in the pipeline; but this is sequence-dependent, so will have not be implemented until new sequence is set</div>Andy
