X-ray machine dynamic imaging control device

Abstract

The invention relates to an X-ray machine dynamic imaging control device which aims to detect images in real time, dynamically acquire images, reduce radiation doses borne by patients, and achieve good imaging quality. The X-ray machine dynamic imaging control device comprises a data acquisition and control device and a voltage and current control circuit, wherein the data acquisition and controldevice comprises an acquisition module, a display module and an intermediate processing module; the acquisition module comprises a low-pass filter GL, a multiplexer MP, an A / D conversion circuit, a display lookup table LUT, a connector CN and a digital serial bus interface; the intermediate processing module comprises an auxiliary bus interface VMC, a buffer memory SDRAM, a digital signal processing chip DSP, a primary video interface integrated circuit PVIA and a neighborhood operation accelerator NOA; and the voltage and current control circuit adopts a singlechip U1 as a core chip of a control system, and the periphery comprises an A / D conversion circuit, a memory CC, an operation indicating lamp LT, 8 sections of digital tube display circuits SJ, an external relay driving circuit CD and a buzzer F.

Description

technical field [0001] The invention relates to an X-ray machine dynamic imaging control device. Background technique [0002] Since the German scientist Roentgen discovered X-rays in 1895, conventional X-ray diagnostic technology applied to the human body has been developed for nearly a hundred years. From the perspective of medical equipment, it is already a relatively mature medical diagnostic technology. Existing medical equipment at home and abroad is mainly based on photography in the use of flat panel detectors. In the fluoroscopy state, that is, dynamic image acquisition, when real-time detection of medical X-rays is required, devices such as image intensifiers are often used. The disadvantages are that the image quality is unclear, the detection sensitivity and image resolution are low, and the acquisition method is more complicated. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior...
