Patent ID: 8502155

Claim:
A radiation sensing device subdivided in N*M pixels, with both N and M at least equal to 3, each pixel having a polygonal surface, wherein the radiation sensing device comprises: a conversion part, adapted to convert, for each pixel, an impinging radiation into an electrical signal having an attribute, a value of said attribute being related to an energy of said impinging radiation for the pixel, a processing part having: for each pixel, at least two counters each associated to a different region of the pixel, a ratio between a total number of counters of the radiation sensing device and a total number of pixels of the radiation sensing device being at least 2, an arbitration circuit adapted, for each pixel: to receive detection information from said pixel and neighbouring pixels, to determine whether detection should be allocated to an elected one of said plurality of counters, taking into account detection information for said pixel and detection information from neighbouring pixels and, in such case, to allocate a detection value to said elected counter.
