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 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.
- Definition Electroporation:
- Dictionary external electrical field to increase the permeability of the cell membrane. It is usually used in molecular biology as a way of introducing some substance into a cell such as a drug, protein, or 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 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.
