Flexible X-ray detector

Abstract

The invention provides a flexible X-ray detector. The flexible X-ray detector comprises a flexible structural member; a flexible imaging sensor fixed inside the flexible structural member, and is usedfor converting an X-ray into an electric signal through the flexible imaging sensor; a circuit board fixed inside the flexible structural member, and is electrically connected with the flexible imaging sensor through a flexible circuit board; and the circuit board comprises a plurality of sub circuit boards, and adjacent sub circuit boards are electrically connected with each other through the flexible circuit board. The flexible X-ray detector provided by the invention can be flexibly bent and deformed, so that the X-ray detector can be used as a flat panel detector and can also be used as acurved surface detector, thus the application range of the X-ray detector is expanded, so that the X-ray detector can better fit an object to be detected, therefore a high-quality image can be obtained, the size and weight of the X-ray detector can be reduced, and the X-ray detector has the characteristics of being anti-falling and durable.

Description

technical field [0001] The invention belongs to the technical field of radiation detection and relates to a flexible X-ray detector. Background technique [0002] X-ray radiation imaging utilizes the short-wavelength and easy-to-penetrate properties of X-rays, and the different characteristics of X-ray absorption by materials with different atomic numbers, densities and thicknesses, and forms images by detecting the intensity of X-rays that pass through objects. Small size, light weight, mobile and portable digital X-ray flat panel detectors are widely used in medical diagnosis, industrial inspection and safety inspection, gradually replacing the traditional X-ray imaging system with film as the recording medium. [0003] X-ray flat panel detector is a kind of X-ray detector widely used at present. Generally speaking, it is a detector that uses semiconductor technology to convert X-ray energy into electrical signals and generate X-ray images. Its energy conversion method ca...

Problems solved by technology

Among them, the existing X-ray imaging sensors are mostly based on amorphous silicon technology, which is generally grown on a glass substrate, which is inflexible and easily broken when encountering impact vibration.

Therefore, in order to protect the X-ray imaging sensor, the existing X-ray flat panel detector usually makes it larger in size and heavier in weight, and because the X-ray flat panel detector is integrated in the flat-shaped structural support, it has a certain High-quality images cannot be obtained when testing objects with curved surfaces

Therefore, X-ray flat panel detectors are not suitable for industrial detection, such as the investigation of cracks in oil pipelines, and occasions that require fast and flexible mobility, such as field hospitals, anti-terrorism and EOD, etc.
