Who invented the first X-ray grid in 1913 that reduced scatter radiation?

• A. Hollis Elmer Potter
• B. William H. Rollins
• C. Gustav Peter Bucky
• D. Wilhelm Roentgen

Answer: (C)

Scatter radiation fogs the image and lowers contrast, because photons deflected from the primary beam reach the film. A grid helps by absorbing those off-angle photons while allowing the primary photons to pass through the gaps, improving image contrast and detail. The first X-ray grid, designed to reduce scatter, was introduced in 1913 by Gustav Peter Bucky. His grid used alternating lead strips with radiolucent spaces placed between the patient and the film, capturing scattered photons before they reach the radiograph. This innovation laid the foundation for grid use in radiography, later refined further by others (like the moving-grid advancements by Hollis Potter) but the initial invention is credited to Bucky.
