Embodiment Construction

[0057] Figure 1A A cross-sectional view of the X-ray image detector 100 according to the embodiment is schematically shown. The detector 100 may include an X-ray absorbing layer 110 and an electronic layer 120 (for example, an ASIC) for processing or analyzing electrical signals generated in the X-ray absorbing layer 110 by incident X-rays. In an embodiment, detector 100 does not include a scintillator. The X-ray absorbing layer 110 may include semiconductor materials such as silicon, germanium, GaAs, CdTe, CdZnTe or combinations thereof. Semiconductors can have high mass attenuation coefficients for x-ray energies of interest.

[0058] as in Figure 1B As shown in the detailed cross-sectional view of the detector 100, according to an embodiment, the X-ray absorbing layer 110 may include one or more discrete regions 114 formed from the first doped region 111 and the second doped region 113 One or more diodes (for example, p-i-n or p-n). The second doped region 113 may be ...

Abstract

Disclosed herein is an apparatus suitable for detecting an image, comprising: a plurality of pixels (150) configured to generate an electric signal upon exposure to a radiation; an electronics system(121) associated with each of the pixels (150), wherein the electronics system (121) comprises a first memory (641) on a first signal path (631) and a second memory (642) on a second signal path (632), both signal paths (631, 632) being between an input terminal (601) and an output terminal (602) of the electronics system (121); wherein each of the first memory (641) and the second memory (642) isconfigured to store the electric signal generated by the pixel (150) the electronics system (121) is associated with, configured to store the electric signal generated in another pixel (150), and configured to transmit the electric signal stored in the electronics system (121) to another pixel (150); wherein the electronics system (121) comprises a switch (610, 620) configured to select one of the signal paths (631, 632).

Description

【Technical field】 [0001] The present disclosure relates to methods of reading data from semiconductor image detectors, particularly semiconductor X-ray image detectors. 【Background technique】 [0002] An X-ray detector may be a device for measuring the flux, spatial distribution, spectral or other properties of X-rays. [0003] X-ray detectors are used in many applications. An important application is imaging. X-ray detectors configured to detect X-ray images may be referred to as X-ray imaging detectors. X-ray imaging is a radiographic technique that can be used to reveal the internal structure of inhomogeneous and opaque objects such as the human body. [0004] Early X-ray detectors used for imaging included photographic negatives and photographic film. The photographic negative can be a glass negative with an emulsion coating. Although photographic negatives have been replaced by photographic films, they are still used in special cases due to the superior quality the...
