Embodiment Construction

[0055] figure 1 An X-ray detector 100 is schematically shown as an example. X-ray detector 100 has an array of pixels 150 . The array may be a rectangular array, a honeycomb array, a hexagonal array, or any other suitable array. Each pixel 150 is configured to detect radiation from a radiation source incident thereon, and may be configured to measure a characteristic of the radiation (eg, the energy, wavelength, and frequency of the particles). For example, each pixel 150 is configured to count the number of photons incident thereon whose energy falls into a plurality of bins over a period of time. All pixels 150 may be configured to count the number of photons within a plurality of energy bins incident thereon during the same time period. Each pixel 150 may have its own analog-to-digital converter (ADC) configured to digitize an analog signal representative of incident photon energy into a digital signal. Pixels 150 may be configured to operate in parallel. For example, ...

Abstract

An X-ray imaging system (10), which is suitable for detecting x-ray, comprises a first X-ray detector (30) and a second X-ray detector (40). The first X-ray detector (30) is configured to move relative to the second X-ray detector (40). A spatial resolution of the first X-ray detector (30) is higher than a spatial resolution of the second X-ray detector (40). A detection area of the first X-ray detector (30) is smaller than a detection area of the second X-ray detector (40). Also provided is a method of X-ray imaging using the X-ray imaging system (10).

Description

[0001] 【Technical field】 [0002] The present disclosure relates to an X-ray imaging system and an X-ray imaging method. [0003] 【Background technique】 [0004] An X-ray detector may be a device for measuring the flux, spatial distribution, spectral or other properties of X-rays. [0005] X-ray detectors are used in many applications. One important application is imaging. X-ray imaging is a radiographic technique that can be used to reveal the internal structure of inhomogeneously composed and opaque objects such as the human body. [0006] Early X-ray detectors used for imaging included photographic plates and photographic film. The photographic plate can be a glass plate with a photosensitive emulsion coating. Although photographic plates were replaced by photographic film, they can still be used in special cases due to the better quality they offer and their excellent stability. Photographic film can be a plastic film (eg, tape or sheet) with a photosensitive emulsion ...
