Problems solved by technology

Due to the low frequency of exposure pulses output by the existing power frequency X-ray high-voltage generator, continuous image acquisition is performed at the same time as exposure, and horizontal stripes caused by exposure dose fluctuations will be seen on the image, which will directly affect image quality. , which in turn affects the diagnostic results, and even the generated images cannot be used normally

Abstract

The invention provides an X-ray exposure calibration method, an image calibration device and an X-ray machine, and relates to the field of image processing, in particular to the X-ray exposure calibration method, the image calibration device and the X-ray machine. The calibration area and the imaging area are arranged in the scanning area of the sensor, and the calibration gray value of each pixel row in the imaging area is calculated according to the calibration area and the imaging area so as to correct the image in the imaging area, so that cross grains generated by exposure dose fluctuation when a power frequency X-ray machine performs continuous image acquisition under exposure can be eliminated; therefore, the image quality is improved, the equipment updating cost is reduced, and the economic benefit is effectively improved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an X-ray exposure calibration method, an image calibration device and an X-ray machine. Background technique [0002] An X-ray machine is a device capable of generating X-rays, mainly including an X-ray tube, a high-voltage generator and a high-voltage cable. The industrial soft ray machine is mainly used for diffraction analyzers for physical and chemical testing. The industrial hard ray machine is mainly used in the detection of thick materials. The X-ray machine used for diagnosis in medicine is called diagnostic X-ray machine, which can be used for fluoroscopy and photographic examination. X-ray fluoroscopy is mainly based on the penetration of X-rays, differential absorption and fluorescence. [0003] The main function of the high voltage generator is to supply the cathode and anode poles of the X-ray tube with DC high voltage and filament heating voltage. Due to the low ...
