William D. Coolidge

William D. Coolidge was an American physicist known for his contributions to the field of radiation biophysics, particularly in the development of x-ray technology. He invented the Coolidge tube in 1913, a type of x-ray tube that improved the generation of x-rays by using a heated filament to produce electrons. This innovation allowed for more precise and powerful x-ray imaging, which has been crucial for medical diagnostics and treatments. His work laid the groundwork for advances in radiology, enabling safer and more effective use of radiation in medicine.
