Embodiment Construction

[0080] Now turning to the attached image, figure 1 Imaging system 10 is diagrammatically shown for acquiring and processing discrete pixel image data. In the illustrated embodiment, imaging system 10 is a digital x-ray system designed in accordance with the present technology to acquire raw image data and process the image data for display. exist figure 1 In the illustrated embodiment, imaging system 10 includes an X-ray radiation source 12 positioned adjacent a collimator 14 . The collimator 14 allows a radiation stream 16 to pass into a region in which a target or subject, such as a patient 18, is located. A portion of the radiation 20 passes or bypasses the object and strikes a digital x-ray detector generally indicated at reference numeral 22 . As will be understood by those skilled in the art, detector 22 may convert x-ray photons received on its surface into lower energy photons and subsequently into electrical signals that are acquired and processed to The image of ...

Abstract

The invention relates to a digital X-ray detector assembly. In one embodiment, a digital X-ray detector (22) is provided with a detector assembly (46) that includes a support panel (72), a digital detector array (54) with a rear side of the detector array (54) being secured to a front side of the support panel (72), a backscattered X-ray and reflected light absorption layer disposed between the detector array (54) and the support panel (72), a rear shock absorbing structure secured to a rear side of the support panel (72), and a front shock absorbing structure (52) secured to a front side of the detector array (54). The digital X-ray detector further includes a shell assembly (34) surrounding the detector assembly (46) and secured to the rear shock absorbing structure.

Description

technical field [0001] The present invention relates to digital imaging systems, and in particular to the assembly of digital X-ray detectors for such systems. Background technique [0002] Many radiological imaging systems of various designs are known and are currently in use. Such systems are generally based on the generation of X-rays which are directed towards the object of interest. The X-rays traverse the object and strike a film or digital detector. In the context of medical diagnostics, for example, such systems can be used to visualize internal tissues and diagnose disease in patients. In other contexts, parts, luggage, packages and other objects may be imaged to assess their contents, among other purposes. [0003] Increasingly, such x-ray systems use digital circuits, such as solid-state detectors, to detect x-rays, which are attenuated, scattered or absorbed by intervening structures in the object. Solid state detectors can generate electrical signals indicat...
