<p><b>New page</b></p><div>== '''DTI scans acquired in '''DICOM''' are not reconstructed properly and cannot be viewed in Slicer''' ==<br />
<br />
'''4-13-05 Test of new script'''<br />
<br />
* The new script after Stephan's code modification is now working properly at least for caseD00779 and caseD00735, which had showed flipped images after reconstruction before.<br />
<br />
1. run /projects/schiz/'''software'''/scripts/lsdi2dwi-all.pl <dir> <case#><br />
<br />
2. open FA images (35 slices) in slicer24 with setting of 0.8593 x 0.8593 x 5, orientation : coronal PA, scalar type : short, Little Endian : yes (*)<br />
<br />
* The FA values shown on the screen in accordance to the pointing of mouse arrow seems to be relevant, e.g. corpus callosum area - 700-900, caudate nuc. 200-250, CSF (3rd ventricle) 0-50.<br />
* Please note that the Little Endian should be yes for adequate image loading.<br />
<br />
<br />'''3-28-05 Update from Sylvain'''<br />
<br />
* Raul and Sylvain have looked at it and it seems that this is a problem only Stephan Maier (or somebody in his group) can solve.<br />
<br />
<br /><br />
<br />
'''3-24-05 UPDATE: PROBLEM'''<br />
<br />
* Three cases were tested for reconstruction of '''dicom''' type DTI image using lsdi2dwi.pl & lsdi2dwi-all.pl. This worked well for caseD00764, but for caseD00735 and caseD00779, the resulting images were flipped.<br />
<br />
<br /><br />
<br />
'''REMINDER***: D files created by lsdi2dwi.pl, and DWI by lsdi2dwi-all.pl, are identical!'''<br />
<br />
* It should be possible to load DWI files into Slicer and "Convert," just as one would for D files<br />
<br />
<br /><br />
<br />
'''3-23-05: Solution'''<br />
<br />
* Sylvain has provided a solution to this problem, which involves the following command:<br />
<br />
* /projects/schiz/'''software'''/scripts/lsdi2dwi-all.pl <dir> <case#><br />
<br />
* This script will reconstruct all x.IMA files into ADC, FAI, DWI, etc. with the case# prefix<br />
** Note: DWI files are the same as "D" files<br />
* A couple reminders:<br />
** If you wish to reconstruct images from the current working directory, be sure to put a "." for <dir><br />
** Don't forget to include the case# in the command line</div>Zack
