[gate-users] Image Reconstruction of Gate output

[Long ZHANG]

Dear Dr. Sadek,

Great job!

I recalled Dr. Claude's suggestion on using root script to study binning
coicidences in root file into sinogram and michelogram. So I hope I can do
something to make your code, together with Dr. Ross's code, into a more generic
binning toolkit, which can support as many as possible scanner types. 

And we may porting the root code into GATE source code (of course, we need Dr.
Morel's offical authorization) in the future.

The first will be DST, which is under heat disscussion now.

Waiting for your positive response and kind help, thank you!

BTW, I was pussled by the sinogram width of DST (420 crystal per ring). The number
249 is larger than the 420/2 = 210. How can DST get the extra LORs of 39? By
interpolation? Could this help to improve the spatial resolution? Thank you!

Cheers,

Long
