1. Roentgenology Rays: Physical Parameters and Imaging Geometry
X-rays are a form of electromagnetic radiation with wavelengths ranging from 0.01 to 10 nanometers (nm). They have shorter wavelengths than ultraviolet (UV) rays and longer wavelengths than gamma rays. X-radiation is also known as Roentgen radiation, named after Wilhelm Conrad Roentgen, who discovered it.
Types of X-rays:
- Soft X-rays: 0.12-12 kiloelectron volts (keV)
- Hard X-rays: 12-120 keV (can
