What ELECTROMAGNETIC RADIATION means: A kind of radiation including visible light, radio waves, gamma rays, and x-rays, in which electric and magnetic fields vary simultaneously. The different forms are differentiated by their wavelength and energy. For instance, visible light has relatively long wavelengths and less energy compared to x-rays or gamma rays with short wavelengths and high energy.
- Definition Electroencephalography (EEG):
- Dictionary electrical activity along the scalp resulting from current flowing within the neurons of the brain. EEG can be used to diagnose epilepsy and other disorders associated with altered brain electrical electromagnetic radiation.
- Definition Exoskeleton:
- Dictionary skeleton that supports and protects an animal’s body in contrast to the bones of an internal skeleton. Rehabilitation engineers have used this design in nature to develop exoskeletons that attach to electromagnetic radiation.
- Definition Endoscope:
- Dictionary flexible or rigid tube-like optical system used to examine the interior of a hollow organ or body cavity by direct insertion. Instruments can be attached for biopsy and surgery. Similar technology is electromagnetic radiation.
- Definition Elastography:
- Dictionary technique that measures the elasticity or stiffness of a tissue. The technique captures snapshots of shear waves, a special type of sound wave, as they move through the tissue. The stiffness of the electromagnetic radiation.
