Radionuclide scanning
A diagnostic examination wherein a radioactive contrast substance is administered intravenously and captured through photography to visualize internal blood vessels, organs, and tissues. A diagnostic method relying on identifying radiation emanating from radioactive substances administered into the body. Various substances are absorbed at varying levels by distinct tissues, enabling the examination of specific organs. For…

Radio waves
Radio waves denote the electromagnetic energy within a frequency range employed in radio communications, typically ranging from 10,000 to 300 billion cycles per second. While radio waves share commonalities with visible light, x-rays, and various other forms of electromagnetic radiation, they possess a higher frequency.

Rotating-anode tube
In the realm of X-ray technology, there exists a specialized apparatus known as a rotating anode X-ray tube. Unlike its stationary counterparts, this particular tube showcases a constantly revolving anode during the exposure process. This continuous rotation serves a vital purpose as it ensures a fresh surface area for electrons to impact, thereby enabling enhanced…

Rotor
The component of an induction motor that undergoes rotation during its functioning is comprised of copper bars strategically positioned around a cylindrical core made of soft iron. Due to its visual resemblance, it is occasionally referred to as a “squirrel cage motor.”
