<BR>
another question about voxelised source :<BR>
I've read the gate user guide section voxelised source and it's<BR>
specified that the source must be translated of its half dimensions on<BR>
negative way.<BR>
<BR>
In my situation, my source has the same dimensions that my phantom<BR>
(matrix of 80x80x270 voxels and the pixel size is 0.4 mm), ie my source<BR>
has the following dimensions : 3.2x3.2x10.8 cm<BR>
<BR>
This translation is specified with the setPosition command for the<BR>
source.<BR>
I think that in my case I have to put the following parameters : <BR>
<BR>
/gate/source/My_source/setPosition -1.6 -1.6 -5.4 cm<BR>
<BR>
Is it right or not? <BR>
<BR>
I have some doubts.<BR>
<BR>
Best regards,<BR>
<BR>
