In PAR/REC version 4.2, this is in one of the columns after the tag ===IMAGE INFORMATION===. The header of that huge table will tell you which column tells you the information (diffusion (ap, fh, rl)) and is a three-float number. Similarly, the b value is in the column labelled diff..<div>

Hello,
<div><br>
</div>
<div>Is there an easy way to find out the [X Y Z] components of the gradient direction for PAR/REC images from a Philips 3T Acheiva scanner? It is no problem to get the magnitude of the directions and b value from the PAR file but I am unsure how to extract
the correct component values. Thank you in advance for any information.</div>
<div><br>
</div>
<div>Best,</div>
<div>Michael<br>
