Embodiment Construction

[0014] The present invention will now be described in further detail with reference to the drawings and embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the constitutions related to the present invention.

[0015] Such as figure 1 As shown, a high-sensitivity image chain system. After the X-rays emitted from the X-ray source pass through the object to be tested, the image intensifier performs image enhancement and converts the X-rays into monochromatic visible light. The visible light is imaged in the digital On the camera, the image capture card is transferred to the computer, and then processed by the image processing software to obtain the corresponding detection image.

[0016] Such as figure 2 As shown, the image intensifier is formed by coupling an intensifying screen and a low-light image intensifier through an electrostatic lens. The intensifying ...

Abstract

The invention relates to a high-sensitivity imaging chain system. After X rays emitted from an X ray source pass through an object to be detected, and are converted into monochromatic visible light by an image intensifier through image intensifying; the visible light is imaged on a digital camera through a lens, is transmitted to a computer by an image acquisition card, and is processed by an image processing software to obtain a corresponding detection image. The high-sensitivity imaging chain system provided by the invention utilizes the image intensifier combined by an intensifying screen and a low light level image intensifier, so that the field of view of imaging is large, the imaging speed is quick, the imaging sensitivity is improved, and clear and high-resolution high-quality images can be obtained.

Description

Technical field [0001] The invention belongs to the field of medical imaging, and particularly relates to a high-sensitivity image chain system. Background technique [0002] The image chain, together with the light path and the imaging sensor, refers to a process that includes using sensor data to reconstruct an image, matching the color of the image, noise reduction, and sharpening, etc., to form a high-quality picture. In X-ray imaging systems, intensifiers are mainly used to convert invisible X-ray images into visible light images, and the brightness of the images is enhanced; the medical system based on X-ray image intensifiers greatly reduces the patient’s experience during diagnosis The X-ray radiation dose is widely used because of it. However, the visible light image generated by the existing image intensifier has low brightness, low image quality, small imaging field, insufficient imaging speed, and low sensitivity; and enhancing image quality has always been a res...
