<div>As I know, x,y,z information is not always necessary.</div>
<div>I have succeeded to load Siemens (Trio, 20 dir) Mosaic files with gradient numbers</div>
<div>You only have to not forget to write numbers of 100, 100, 100 and finally 0,0,0 at the end of table.</div>
<div>Here is an example,</div>
<div> </div>
<div>0: -1.000000, 0.000000, 0.000000<br>1: 0.000000, -1.000000, 0.000000<br>2: 0.031984, -0.799591, 0.599693</div>
<div>.</div>
<div>.</div>
<div>.</div>
<div>18: -0.111012, -0.264029, -0.958105<br>19: -0.031984, -0.799591, -0.599693<br>20: 100, 100, 100<br>21: 0,0,0<br> </div>
<div>If you really want to find the x,y,z information, I'm afraid I can't answer it.</div>
<div>But I have heard that the information is not technically necessary from the computer technologist</div>
<div>working at the Siemens company. He have read the instructions and talked to me like that.</div>
<div> </div>
<div>Wish it would be helpful.</div>
<div> </div>
<div>Regards,</div>

<div dir="ltr">Hello all,<br><br>I sent out an e-mail earlier about generating a gradient table and am still a little bit confused. In order to use DtiStudio properly, it seems that one needs a gradient table to go along with their data. Our lab is currently using a 3T Excite GE scanner to perform our DTI scans, but we also have a Siemens scanner for which the following questions apply. Within the dicom header of the GE scanner, under the tag #DTI Diffusion Dir (0019, 01E0), we are able to tell the number of gradients, but not able to find the x,y,z information. <br>
<br>Is there a program that can generate gradient tables to go along with our dicom data, or can it actually be found within the header - and if so, where? Finally I was curious as to whether there are standard gradient tables that go along with specific scanners every time a DTI scan is performed.<br>
<br>Thank you very much for all of your help, it is much appreciated.<br><br>Sincerely,<br><br>Tapan Jani<br><br><a onclick="return top.js.OpenExtLink(window,event,this)" href="mailto:tjani2@uic.edu" target="_blank">tjani2@uic.edu</a><br>
