Basic Introduction to X-ray Grids
The anti-scatter grid is an essential supporting accessory for X-ray and DR imaging equipment, widely matched with chest stands and radiographic tables. Its core function is to filter scattered rays and optimize image quality.
When X-rays penetrate the human body, a large number of scattered rays will be generated. These messy stray rays cause blurry images, reduced contrast and missing details, affecting diagnostic accuracy. The filter grid effectively blocks invalid scattered rays and retains effective vertical X-rays, making bone and soft tissue images clearer.
It is mainly composed of lead strips, spacing materials and protective plates. High-density lead strips block scattered rays; the isolation layer ensures the penetration of useful rays; the outer protective structure strengthens durability.
Anti-scatter grids include fixed and moving types, suitable for hospital radiology departments, primary medical centers and mobile physical examination vehicles, being essential parts of medical X-ray shooting.
