Hi:<br>
<br>
I got the following gradient directions table from the DICOM TAG (19, 100E):<br>
<br>
1: 0.70817843 0.00571112 -0.70389509<br>
<br>
2: 0.70889196 -0.00570537 0.70318659<br>
<br>
3: 0.03170213 0.0 -0.03170213<br>
<br>
4: 0.03168621 0.0 -0.03168621<br>
<br>
5: 0.70427267 -0.70853239 0.00567962<br>
<br>
6: 0.7039208 0.70959758 0.00425759<br>
<br>
<br>
Why the directions 3 and 4 are equal ?...<br>
<br>
Sincerely,<br>
<br>
