X-ray imaging device

Abstract

An x-ray imaging device comprises an x-ray light source, a light homogenizing element, a fluorescent screen, an image sensor, an image signal processing module, a display device and a wireless delivery module; wherein the x-ray light source is used for launching the x-ray to an object to be measured; the light homogenizing element is provided with a plurality of lens; the index of refraction of the lens far from the centre of the light homogenizing element is greater than the index of refraction of the lens close to the light homogenizing element; the fluorescent screen is arranged between the x-ray light source and the light homogenizing element and is used for converting the x-ray into visible light; the image sensor is used for sensing optical lines passing through the light homogenizing element and converting the optical lines into electrical signals; the image signal processing module is electrically connected with the image sensor and is used for processing the electrical signals to obtain image signals of the object to be measured; the display device is eclectically connected with the image signal processing module and is used for obtaining the image signals and displaying the image of the object to be measured; the wireless delivery module is electrically connected with the image signal processing module and is used for transmitting the image signals in the radio wave form.

Description

technical field [0001] The invention relates to X-ray imaging technology, in particular to an X-ray imaging device. Background technique [0002] X-ray imaging is widely used in human body imaging and medicine. Since the absorption of X-rays by different organs and tissues of the human body can be characterized by tissue density, X-ray fluoroscopy and X-ray radiography have been developed to diagnose and locate diseases or injuries of human bones, internal organs and blood vessels. Film was brought into the field of medical imaging, making it the tool for image display and information storage for more than 100 years. [0003] However, since the size of the particles used in film imaging has been limited, it is very difficult to further overcome factors such as particle inhomogeneity, and the film limits the further improvement of image quality (see Zhang Shigang, Xie Yaoqin and Bao Shanglian in China " Physics, Volume 33, Issue 10, titled "The Current Status and Future of ...

Problems solved by technology

[0003] However, since the size of the particles used in film imaging has been limited, it is very difficult to further overcome factors such as particle inhomogeneity, and the film limits the further improvement of image quality (see Zhang Shigang, Xie Yaoqin and Bao Shanglian in China " Physics, Vol. 33, No. 10, a paper titled "Current Status and Future of Medical Imaging Physics"

Moreover, film imaging is time-consuming, which affects the speed of diagnosis
