    Area of Science:

    • Radiological Physics
    • Medical Imaging Technology

    Background:

    • Conventional linear grids are essential for reducing scatter radiation in X-ray imaging.
    • Improving scatter rejection efficiency is crucial for enhancing diagnostic image quality and reducing patient dose.

    Purpose of the Study:

    • To introduce and evaluate a novel zigzag grid design for improved scatter radiation reduction.
    • To compare the scatter transmission performance of ideal zigzag grids against ideal linear grids.

    Main Methods:

    • Construction of geometrically ideal linear and zigzag grids with identical thickness and lead content.
    • Experimental testing of both grid types to measure transmitted scatter radiation.

    Main Results:

    • The ideal zigzag grid demonstrated a 50% reduction in transmitted scatter compared to the ideal linear grid.
