T-rays

Tetraherz radiation, electromagnetic radiation of wavelength lying between the infrared and microwave radio waves. A method of generating T-waves has recently been developed and this radiation has been shown to be effective in detecting the precise extent of cancers lying immediately below the surface of the skin.
