[Gate-users] A multi-system detector

[Marc Chamberland]

Hi Sonoko,

I think you should look at the volume ID of the hit. With a little investigating, you can figure out the volume ID of all your detectors. A few things to note:

1) When you use a ring repeater, the volume ID increases in a counter-clockwise direction around the rotation axis.

2) In a cubic array repeater, the volume ID increases first along x, then along y, then along z.

Hope this helps!
Marc

Hello Gate users,

I have defined a multiple-system detector with several SPECT heads.
Now I am looking at testSingles.dat file.

Can some one tell me how to know which hit is from which SPECT head?

In testSingles.dat, column 12, 13 and 14 are the hit's coordinate of (x,y,z).
But how can I know that these hist are from SPECT_head1, SPECT_head2, SPECT_head3, etc...???

Thank you in advance for your help.

Sonoko
