Answer:
Thomas Alva Edison.
Step-by-step explanation:
Edison developed a cellulose nitrate film that was transparent, flexible, and could be coated with a light-sensitive emulsion to capture x-ray images. This film base revolutionized the field of radiology by providing a safer and more efficient way to capture and view x-ray images. Prior to Edison's invention, glass plates were commonly used as the base for x-ray images, but they were heavy, fragile, and prone to breakage. The introduction of cellulose nitrate film made it easier to handle, store, and transport x-ray images, while still maintaining the necessary image quality. Edison's invention paved the way for advancements in medical imaging and laid the foundation for modern radiology techniques.
