Scanner (radio) A scanner (also referred to a police scanner, police scanner radio or radio scanner) is a radio receiver that can automatically tune, or scan, two or more discrete frequencies, stopping when it finds a signal on one of them and then continuing to scan other frequencies when the initial transmission ceases.
MRI (magnetic resonance imaging) is a fairly new technique that has been used since the beginning of the 1980s. The MRI scaner uses magnetic and radio waves to create pictures of tissues, organs and other structures within the body, which can then be viewed on a computer. This means that, unlike some other modes of medical imaging, there is no exposure to X-rays or any other damaging forms of radiation.
