What is the modern x-ray tube commonly known as?

The modern x-ray tube is commonly known as the Coolidge tube. This designation comes from the name of William Coolidge, who developed this type of x-ray tube in 1913. The Coolidge tube is an improvement over earlier designs, primarily due to its use of a heated filament, which allows for greater control over electron emission and, consequently, better image quality and exposure times.

This tube design significantly advanced the field of radiology, leading to safer and more effective x-ray imaging. The introduction of the Coolidge tube made it possible to produce high-quality diagnostic images while reducing the risks associated with radiation exposure. Thus, the term "Coolidge tube" is synonymous with modern x-ray technology and represents a pivotal moment in medical imaging history.
