Patent ID: 7605375

Claim:
An Application Specific Integrated Circuit for use as a readout for one of radiation detection and radiation imaging, comprising: plural pixel cells, each pixel cell arranged to receive an input of an electric charge from an output of a corresponding different imaging cell of a radiation imaging detector, each said pixel cell comprised of i) an input connection, the input connection for connecting to the output of the corresponding different imaging cell, said connection to receive the electric charge generated in response to incident radiation events on the detector; and ii) a circuit connected to said input connection, said circuit for receiving and processing the charge and selectively operable to perform two or more functionalities based on processing the charge, wherein each said circuit comprises a counter and a mode logic operatively connected said counter for setting said counter to perform, selectively, at least two of a) photon counting, b) analog to digital conversion of the one of the voltage amplitude and the current amplitude, and c) timing measurement of incident radiation events.
