Dear all,

I am a Philips Achieva system user and recently started using DTI studio.
A given gradient table for DTI_low is as follows:

1.0000 0.0000 0.0000
0.0000 1.0000 0.0000
0.0000 0.0000 1.0000
-0.7044 -0.0881 -0.7044
0.7044 0.7044 0.0881
0.0881 0.7044 0.7044
0.0000 0.0000 0.0000

So I use gradient table in DTI with following table.
Somehow, b0 is located at the last.

0:1.0000, 0.0000, 0.0000
1:0.0000, 1.0000, 0.0000
2:0.0000, 0.0000, 1.0000
3:-0.7044, -0.0881, -0.7044
4:0.7044, 0.7044, 0.0881
5:0.0881, 0.7044, 0.7044
6:0.0000, 0.0000, 0.0000

Philips system DTI output image start with b0 image.
I wonder if I am using the right table or in the right order for gradients.

Best,

Seongjin
