Description

Multi-direction X-ray imaging system with stable imaging

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to multi-direction X-ray imaging system that formation of image is stable.

Background

In the operation process of cardio-cerebral angiography, fracture repair, joint replacement, scoliosis correction and the like in hospitals, doctors must use an X-ray machine imaging system commonly used in interventional operations for a long time, such as a large DSA imaging system and a C-arm X-ray machine, to observe the condition of angiography or fracture of a patient in real time. The C-arm X-ray machine can only image the region of the human body from one direction, so for more complicated operations, the doctor needs to observe from 2 or more directions, which is not enough. Large Digital Subtraction (DSA) systems have both monoplane imaging and biplane imaging. The digital subtraction system for single plane imaging also only allows a doctor to see the result of angiography in one direction, and cannot correctly image the blood vessel parallel to the imaging direction. The digital subtraction system for biplane imaging can image the cardiovascular and cerebrovascular vessels from two directions simultaneously, so that the image blind area which often appears when the digital subtraction system for single-plane imaging is used is avoided. Although the digital subtraction system for biplane imaging solves the problem of the DSA imaging system for single-plane imaging, the digital subtraction system for biplane imaging has the disadvantages of huge equipment, high cost and complex use, and can be used only in large hospitals. In addition, the digital subtraction system for biplane imaging can only perform simultaneous imaging in two directions at most, and cannot perform X-ray imaging in more directions.
