Production device of filter line plate for X-ray machine

Abstract

The invention provides a production device of a filter line plate for an X-ray machine. The production device comprises a workbench, wherein a vertical frame is arranged on the workbench; the upper parts of the vertical frame and a swing frame are connected through a bearing, and the middle parts of the vertical frame and the swing frame are connected through an air cylinder; the swing frame can do pendulum motion by taking a bearing connecting part of the vertical frame and the swing frame as a circle center under the driving of the air cylinder; sliding assemblies are arranged on the two sides of the upper surface of the workbench; sliding seats are arranged on the sliding assemblies; a connecting assembly and a raw material frame assembly are arranged between the sliding seats on the two sides of the workbench in parallel; the connecting assembly can rotate between the sliding seats by taking the axis of the connecting assembly as a center; the upper part of the connecting assemblyis movably connected with the swing frame, and the lower part of the connecting assembly is movably connected with a feeding frame; the feeding frame can swing along with the swing frame at the same frequency and the same amplitude; raw materials are arranged on the raw material frame assembly; the raw materials pass through the feeding frame; and the feeding frame impacts the raw materials on a baffle of the workbench in a reciprocating mode under the action of the air cylinder along with the swing frame. According to the filter line plate produced by the device, the resolution and the definition of a film image are greatly improved.

Description

Technical field: [0001] The invention belongs to the field of medical imaging, and mainly relates to a production device for film-taking by an X-ray machine and a filter plate for a gastrointestinal machine. Background technique: [0002] In X-ray imaging, due to the Compton effect, when the original emission ray emitted from the X-ray tube enters human tissue, it will produce scattered rays with longer wavelengths than the original emission ray, such as figure 1 As shown, the scattered rays radiate in random directions, and the thicker the inspected part, the more scattered rays will be generated. When the scattered rays act on the X-ray film, background fog will be formed on the film, resulting in the resolution, clarity, and Contrast, etc. are significantly lowered. [0003] The filter plate is placed between the human body and the film. The more grids on the filter plate, the more the scattered rays will be filtered. Most of the grids are converging grids, that is, each...

AI Technical Summary

Problems solved by technology

[0004] At present, my country's filter plates mainly rely on imports. Due to technical barriers, the domestically produced filter plates have relatively thin grids, resulting in low resolution and clarity of film images, which cannot correctly reflect the location of lesions. Specific circumstances may lead to misdiagnosis
