<p>Update from Wiki</p> <p><b>New page</b></p><div>'''GOALS'''<br /> <br /> * '''May - October 2005''' (A. Song)<br /> ** Pulse sequences will be tested at different platform, and a common acquisition protocol will be recommended by taking individual scanner's limitation into account.<br /> ** Universal recon and correction software for GE/Siemens/Philips is being planned. The original Matlab code developed for GE scanner is being re-written in visual C++, a working version should be available by mid-June, and final version should be on time for 10/2005 meeting.<br /> ** Expand the recon and correction software for SENSE EPI acquisition used for DTI acquisition at many sites, including JHU who uses this exclusively now.<br /> ** Implement spiral based DTI imaging using the same field map to de-blur the images at different diffusion weighting directions.<br /> <br /> ----<br /> <br /> ----<br /> <br /> &lt;br /&gt;'''UPDATES'''<br /> <br /> * '''Progress for May 2005 - July 2005''' (A. Song)<br /> ** Manuscript recommended for publication pending revision at NeuroImage. The revision was sent in at the end of June.<br /> ** Pulse sequence and correction procedure completed on GE system for 64x64 and 128x128 DTI images.<br /> ** Correction algorithm ported to C-program and the correction procedure is now being standardized into a &quot;plug-in&quot; for any platform, using ANALYZE image format. Additional formats are being considered such as the BXH (BIAC XML HEADER).<br /> ** Pulse sequence completed by Brian Soher on the Siemens 3T. He is currently adapting our recon program to generate identical matched field maps to interface with our correction procedure.<br /> ** Pulse sequence being ported to Philips.<br /> ** Local full-time post-doc is still being hired to facilitate the aforementioned development. Currently, Mr. Bin Chen, a third year Duke BME graduate student is engaged in primary development along with myself.<br /> <br /> &lt;br /&gt;<br /> <br /> * '''Progress for October 2004 - May 2005''' (A. Song)<br /> ** Manuscript under review at NeuroImage, the corresponding abstract was well received during ISMRM in Miami.<br /> ** Pulse sequence completed on GE system, and currently being ported to Siemens 3T at Duke. I am working with Brian Soher here at Duke for this project.<br /> ** Pulse sequence being ported to Philips, working with Susumu Mori at JHU. It seems now that we have a working patch (with help from Raja Muthupillai, Philips Medical Systems) to run the pulse sequence.<br /> ** Local full-time post-doc is still being hired to facilitate the aforementioned development. Currently, Mr. Bin Chen, a third year Duke BME graduate student is taking half the cost until the post-doc is identified. We are in the process of inteviewing post-doc candidates. The alternative plan is for me to recruit another BME grad student along with Bin Chen for more man power.<br /> <br /> ----</div>
