ABSTRACT:
A method and apparatus for measuring electrical or magnetic fields, such as high-frequency alternating fields in a nuclear magnetic resonance tomography device, convert a test signal into a corresponding ultrasound signal, and transmit the ultrasound signal to a receiver, where the received signal is converted back into an electrical signal. The transmission path contains no metallic components and thus does not cause any disturbance in the field being measured.
