    摘要： A radiation imaging device includes plural individual detectors defining an irregular rectangular active area responsive to x-rays and with different widths along a length of the active area. The individual detectors may be of different rectangular shapes and mounted on a motherboard. The motherboard may be formed of a first module mounting a first of two individual detectors and a second module detachable connected to the first module and mounting a second of two individual detectors.

    摘要： A radiation device includes a detector connected to a multi-functional radiation identifying and processing application specific integrated circuit. The detector includes a plurality of individual imaging cells, each imaging cell generating a charge in response to incident radiation events and outputting the generated charge at an imaging cell output. The application specific integrated circuit includes a different circuit connected respectively to a corresponding one of the imaging cell outputs, each circuit receiving and processing the generated charge received from the corresponding one imaging cell output. Each circuit includes a preamplifier for generating a voltage or current amplitude in response to the received charge, a counter, and a mode logic configured for setting the 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.

The detector also comprises a first semiconductor element (101) being coupled with said neutron reactive material (102) and adapted to interact with said ionizing radiation reaction products and provide electrical charges proportional to the energy of said ionizing radiation reaction products. In addition electrodes are arranged in connection with said first semiconductor element (101) for providing charge collecting areas (106) for collecting the electrical charges and to provide electrically readable signal proportional to said collected electrical charges. In the detector (100) the neutron reactive material is arranged so that the incident neutrons to be detected interact with the neutron reactive material (102) essentially in the portion nearest to said charge collecting areas (106, 110) provided by the electrodes in said first semiconductor element (101) to which said neutron reactive material is coupled with.
