Abstract:
The invention relates a photon counting device and method for counting photon interactions in a piece of converter material and addressing the issue of charge sharing. The occurrence of a charge sharing event is already detected upon the onset of the pulse, taking into consideration an onset of a pulse in a neighboring pixel within a preferably very short coincidence window. According to the invention, it is detected whether a pulse is being processed and one or more neighboring pixels are scouted to decide whether a simultaneous interaction has been registered within a very short coincidence window.

Claim (Index 1):
A photon counting device for counting photon interactions in a piece of converter material, comprising:\n a plurality of energy discriminators and a pulse detector, each being arranged to receive a pulse generated by a photon interacting with the piece of converter material, and a plurality of counters, each of the counters being coupled to one of the energy discriminators, for counting photon interactions with energy discrimination according to an energy level of the coupled energy discriminator, wherein the pulse detector is arranged to provide a pulse logic signal upon receiving an input of a predetermined energy level, the predetermined energy level being lower than the energy levels of the energy discriminators, wherein the photon counting device further comprises a prevention circuitry arranged to receive a neighboring logic signal indicating an input of predetermined energy level in at least one neighboring piece of converter material, wherein the prevention circuitry is arranged to selectively prevent a pulse from being counted by any one of the plurality of counters in case the pulse logic signal and the neighboring logic signal are present together in a coincidence window of predetermined size.
