A system for automatically adjusting gray level of X-ray film image

Abstract

A system for automatically adjusting gray level of an X-ray film image takes advantage of a load plate, an X-ray aperture, a ray tube, an X-ray detector, X-rays, high pressure generating devices, a detection device, a central proces unit, an X-ray film processing apparatus, an image processing apparatus, a parameter input device and a display device. Through the processing of the image processingapparatus, the X-ray image can be clearly displayed, An X-ray diaphragm irradiates X-rays onto a subject, X-rays transmitted through the subject are projected to an X-ray detector, an X-ray detector detects X-rays, and converts the detection result into an electric signal and transmitting the electric signal to the detection device, the detection device transmits the electric signal to the centralprocessing device, the central processing device transmits the electric signal to the X-ray film processing device, the X-ray film processing device forms the image information of the subject based on the electric signal transmitted from the X-ray detector through the detection device, and the parameter input device is used for adjusting the gradation range of the image information.

Description

technical field [0001] The invention relates to the field of X-ray film testing, in particular to an automatic gray scale adjustment system for X-ray film images. Background technique [0002] In the process of digital imaging, due to physical and technical reasons such as equipment, electrical noise, X-ray scattering, the complexity of the object being shot, and technology, the image quality is often unsatisfactory, often manifested in dark images and poor contrast. , The target area is blurred, it is difficult to analyze and identify the target, so that a correct judgment cannot be made. For this reason, it is necessary to enhance the contrast of the image, improve the contrast, and highlight the target area, but the situation is often with the target area in the image. enhancement, the background area is also enhanced at the same time, but the target cannot be clearly highlighted. Therefore, it is necessary to provide an automatic adjustment system for the gray scale of t...
