[Gate-users] Perfect detector

Hi there,

I am trying to simulate a simple test case, e.g. a tiny cube of iron, 
one micrometre, with a single projection using an X-ray tube.
So I use a CTscanner type of detector (using 'fast' as example) and only 
simulate one projection.
It is 100x100 micrometres.

Is there any (easy) way to simulate a perfect detector in Gate (update 
the pixel values at locations corresponding to the front surface of the 
detector, i.e. for that application we do not need to take care of the 
interaction within the detector),
and integrate the energy fluence and/or particle fluence,
and store the projections using /gate/output/imageCT/?
(I guess it does not matter with the root output)

Is it possible to store only the direct radiation, i.e. photons that do 
not interact with my test object, using /gate/output/imageCT/?
or filter the output so that only Compton is taken into account?

Best Regards,
