[gate-users] Supported Scanners

[Mutanga Theodore]

Thanks for clarifying that Ross, at
 least now I know the limitations of my design. What about using the .ima
and .dim files from the sinogram outputs? what can be used to read those
? Given that one is only interested in the basic parameters of the DST
scanner ,- NEC , resolution and sensitivity whicih system will be best
for the DST then ? I was hoping I could at least get some form of
reconstructed image of a point source so that I could calculate the
spatial resolution.

In the example of the Hoffman phantom , what was used to produce the
images I saw on the documentation website ?

Cheers
Theo
