'''Project'''<nowiki>: Non-rigid EPI registration using ITK </nowiki>

'''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>

'''Impact'''<nowiki>: Medium (Saykin) </nowiki>

'''Difficulty'''<nowiki>: Medium (Tuch) </nowiki>

'''Vision'''<nowiki>: Software tool which can perform robust non-rigid, intrasubject registration between an EPI image and a conventional structural image. </nowiki>

'''Goal'''<nowiki>: Identify optimal ITK method and parameter settings for non-rigid intrasubject registration of T2 EPI to T1 conventional. Provide software devliverable. </nowiki>

'''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

 DTI data] and [https://portal.nbirn.net/BIRN/cgi-bin/DataGrid/browse.cgi?browseloc=/home/Projects/NAMIC__0003/Files/Dartmouth/HealthyControls6/SPGRdata

conventional data].

'''Team members'''<nowiki>: Snyder, Jen, Tuch, Ibanez </nowiki>

<br />'''Win conditions'''<nowiki>: </nowiki>

'''Kitware'''<nowiki>: Demonstration of advantages of ITK solution. Practical implementation towards DBP. </nowiki>

'''MGH'''<nowiki>: Guidance on optimal use of ITK non-rigid registration functions </nowiki>

'''Dartmouth'''<nowiki>: Software deliverable </nowiki>

<br />'''Most probable failure modes'''<nowiki>: </nowiki>

* Loss of traction

* Insufficient accuracy

* Ambiguous accuracy results (E.g., registration performance inconsistent across subjects or regions)
