Who invented the first X-ray grid?

• A. Gustav Peter Bucky
• B. Hollis Elmer Potter
• C. William H. Rollins
• D. Clarence Dally

Answer: (A)

X-ray grids exist to cut down scattered radiation and boost image contrast. The first practical grid was invented by Gustav Peter Bucky in 1913. He introduced a grid made of lead strips that absorb scatter before it reaches the film, which markedly improves image quality. Later, Hollis Elmer Potter helped refine the concept by developing the moving grid (the Potter-Bucky grid), which prevents grid lines from appearing on the radiograph. While William H. Rollins contributed important safety advances and Clarence Dally is known for early radiation exposure injuries, neither invented the first grid.
