摘要： An imaging system includes a scintillator array (202) and a digital photomultiplier array (204). A photon counting channel (212), an integrating channel (210), and a moment generating channel (214) process the output signal of the digital photomultiplier array (204). A reconstructor (122) spectrally resolves the first, the second and the third output signals.

An imaging system includes at least one direct conversion layer (302) and at least two scintillator layers (304) and corresponding photosensors (306). A photon counting channel (212) processes an output of the at least one direct conversion layer (302), and an integrating channel (210) and a moment generating channel (214) process respective outputs of the photosensors (306). A reconstructor (122) spectrally resolves the first, the second and the third output signals.

摘要： The invention relates to an addressing circuit for an array arrangement (100) of electronic units (101), which may be, for example, pixels of an X-ray detector. Every pixel (101) is connected to a spatially adjacent shift register (110), the shift registers (110) being connected in turn column-wise in series and also being connected to a common clock line (111,114). A trigger signal fed via an external trigger line (113) is passed by the shift registers (110) from row to row for every clock signal on the clock lines (111,114). In this process, triggered shift registers (110) activate the associate pixels (101) so that they can be read out via read-out lines (105) that extend column-wise.

摘要： An x-ray detector and its pixel circuit are described, that allow to cover a large dynamic range with automatic selection of the sensitivity setting in each pixel, thus providing improved signal to noise ratio with all exposure levels. X-ray detectors are required to cover a large dynamic range. The largest exposure determines the required pixel capacitance. However, a large pixel capacitance gives a bad signal to noise ratio with small exposures e.g. in the dark parts of the image. This invention disclosure describes several approaches to provide automatic sensitivity selection in the pixels. This ensures that low signals are stored in a small capacitor or read out with a high sensitivity with corresponding good signal to noise ratio, while larger signals are stored in larger capacitors or are read out with lower sensitivity so that no information is lost.
摘要翻译：描述了X射线检测器及其像素电路，其允许通过自动选择每个像素中的灵敏度设置来覆盖大的动态范围，从而在所有曝光水平提供改善的信噪比。 X射线探测器需要覆盖大的动态范围。最大的曝光决定所需的像素电容。然而，较大的像素电容给出了较小的曝光率的信噪比差。在图像的黑暗部分。本发明公开描述了在像素中提供自动灵敏度选择的几种方法。这确保了低信号被存储在小电容器中或以高灵敏度读出，具有相应的良好的信噪比，而较大的信号存储在较大的电容器中，或者以较低的灵敏度读出，从而不会丢失任何信息。
