摘要： The present invention relates to an indirect radiation detector for detecting radiation (X), e.g. for medical imaging systems. The detector has an array of pixels (P1-P6), each pixel (P) being sub-divided into at least a first and a second sub-pixel (PEl, PE2). Each sub-pixel has a cross- sectional area (Al, A2) parallel to a surface plane (60) of the array. The cross-sectional area (Al) of the first sub-pixel (PEl) is different, e.g. smaller, from the cross- sectional area (A2) of the second sub-pixel (PE2) to provide a dynamic range of detectable flux densities. Additionally, the first sub-pixel (PEl) has a photosensitive device (PSl) arranged on a side of the sub-pixel, said side being substantially orthogonal to said surface plane of the array of pixels to provide a good optical coupling. The detector allows high-flux photon counting with a relatively simple detector design.

摘要： An apparatus receives signals generated by a detector (100) sensitive to ionizing radiation such as x-rays. A differentiator (204) generates an output indicative of the rate of change of the detector signal. A discriminator (206) classifies the amplitude of the differentiator (204) output. An integrator (208) triggered by the output of the discriminator (206) generates outputs indicative of the detected photons. One or more correctors (24a, 24b) corrects for pulse-pileups, and a combiner (25) uses the outputs of the correctors (24a, 24b) to generate an output signal indicative of the number and energy distribution of the detected photons.
