Image processing in real-time and display device for digital X ray equipment

Abstract

The invention relates to a real-time image processing and display device of a digital X-ray equipment, including: an image processing module, which receives the external image data by an image input module for processing; an image display and storage module, which receives data processed by the image processing module and outputs to the image display device; a microcontroller, which controls the actions of the image processing module and the image display and storage module according to the command of a main control equipment of the X-ray machine which is sent from an external interface; an image processing storage, which is connected with an image processing and storage controller in the image processing module; an image display cache memory, which is connected with an image display cache memory controller in the image display and storage module, and an image storage, which is connected with an image storage controller in the image display and storage module. The invention is stable, reliable and fast in image processing speed; furthermore, the invention has the functions of real-time image processing, displaying and replaying of the medial images, displaying and real-time image subtraction of the reference image under the perspective or continuous exposure mode, as well as providing the data to a computer and so on.

Description

technical field [0001] The invention relates to digital X-ray equipment in the technical field of medical equipment, in particular to a real-time image processing and display device of the digital X-ray equipment. Background technique [0002] In traditional technology, the image system of digital X-ray equipment is generally composed of the following parts: the image data receiving part, the X-rays enter the CCD (Charge Coupled Device, Charge Coupled Device) after filtering the wire grid and the image intensifier, and the CCD uses a low-voltage differential signal (LVDS) to transmit image data; image processing part, commonly used X-ray image processing algorithms include noise reduction, subtraction, edge enhancement, motion detection, image rotation, pincushion distortion correction, etc.; image display and archiving part, complete image in Display on CRT or liquid crystal display, and complete document archiving, editing and other work according to user requirements.
