Due to a lack of financial resources, we unfortunately have to suspend the import of any new radio frequency and mobile phone-related articles as of now (November 27, 2017). We apologize for this inconvenience and will keep you informed.

Because we received a large number of inquiries, we set up a bank account to accept donations. With their aid, we hope to resume, at least partly, the import of newly published articles to the RF archive of the EMF-Portal. Any contribution is greatly appreciated. Thank you for your kind support!

magnetic resonance imaging

  • MRI
  • NMR
Medical technology. A technique for visualizing internal stuctures of the body, particularly the soft tissues. The object to be viewed is exposed to a strong magnetic field. The atomic cores (e.g., hydrogen atoms) take a certain orientation within the magnetic field. By a radio-frequency pulse, this orientation is deranged. When the nuclei take back their orientation after the pulse, they emit an electromagnetic signal, which is used to give the picture.
