X-rays are created in machines by passing an current between two electrodes in a vacuum tube. As the electrons hit the positive electrode and are decelerated, X-rays are generated. X-rays are commonly used to visualize broken bones in hospitals but are also used in CAT scans, bone densitometry scans, and fluoroscopy procedures.
Radiographers/radiologic technologists use ionizing energy in the form of x-rays utilizing sophisticated equipment to generate images (radiographs) of an injury or disease process.
