<p>Update from Wiki</p>
<p><b>New page</b></p><div>'''Project'''<nowiki>: Non-rigid EPI registration using ITK </nowiki><br />
<br />
'''Use case'''<nowiki>: 'I'd like to be able to register an EPI image to a conventional structural image. This will help correct for the distortions in EPI images, and help me use tools which have been developed for conventional structural images' - Saykin </nowiki><br />
<br />
'''Impact'''<nowiki>: Medium (Saykin) </nowiki><br />
<br />
'''Difficulty'''<nowiki>: Medium (Tuch) </nowiki><br />

<br />
'''Vision'''<nowiki>: Software tool which can perform robust non-rigid, intrasubject registration between an EPI image and a conventional structural image. </nowiki><br />
<br />
'''Goal'''<nowiki>: Identify optimal ITK method and parameter settings for non-rigid intrasubject registration of T2 EPI to T1 conventional. Provide software devliverable. </nowiki><br />
<br />
'''Test Data'''<nowiki>: We'll look at all 6 healthy individuals from the Dartmouth data set. [</nowiki>https://portal.nbirn.net/BIRN/cgi-bin/DataGrid/browse.cgi?browseloc=/home/Projects/NAMIC__0003/Files/Dartmouth/HealthyControls6/DTIdata<br />

DTI data] and [https://portal.nbirn.net/BIRN/cgi-bin/DataGrid/browse.cgi?browseloc=/home/Projects/NAMIC__0003/Files/Dartmouth/HealthyControls6/SPGRdata<br />
<br />
conventional data].<br />
<br />
'''Team members'''<nowiki>: Snyder, Jen, Tuch, Ibanez </nowiki><br />
<br />
<br />'''Win conditions'''<nowiki>: </nowiki><br />
<br />
'''Kitware'''<nowiki>: Demonstration of advantages of ITK solution. Practical implementation towards DBP. </nowiki><br />
<br />
'''MGH'''<nowiki>: Guidance on optimal use of ITK non-rigid registration functions </nowiki><br />
<br />
'''Dartmouth'''<nowiki>: Software deliverable </nowiki><br />
<br />
<br />'''Most probable failure modes'''<nowiki>: </nowiki><br />
<br />
* Loss of traction<br />
<br />
* Insufficient accuracy<br />
<br />
* Ambiguous accuracy results (E.g., registration performance inconsistent across subjects or regions)<br />
