I need to create a sort of "collimator" to apply to my fluorescence detector.
The setup is the following: an xray source hits a water phantom containing a small cylinder of gold that emits fluorescence.
I pixelated the detector in order to create a sort of image of my phantom (obtaining the distribution of x rays in correspondance of the position of the cylinder).
What I would like to do is to select the photons passing through my detector on an angular basis. Is it possible to store the exact position of emission (and then calculate the angle knowing the final position in the detector)?Or maybe is there another way to do that?
Thank you so much for any suggestion
