Abstract
A magnetic resonance examination apparatus includes a coil system (10) for receiving spin resonance signals generated in an examination zone, and a processing unit remote from the examination zone for processing the signals received in the coil system. Disturbing effects are liable to occur when a coil system is connected to the processing unit via a cable. These disturbing effects are avoided in that in the direct vicinity of the coil system there is arranged a transmitter for transmitting the spin resonance signals. This transmitter cooperates in a wireless fashion with a receiver to which the processing unit is connected.
Claims20
A magnetic resonance examination apparatus, comprising a receiving coil system for receiving spin resonance signals generated in an examination zone, and a processing unit remote from the examination zone for processing the signals received by the receiving coil system, characterized in that in the direct vicinity of the receiving coil system there is arranged a transmitter connected to the receiving coil system for transmitting high frequency signals derived from the spin resonance signals received by said receiving coil system, in a wireless fashion, to a receiver connected to the processing unit.
A magnetic resonance examination apparatus comprising:
- a transmitter coil system for producing a high-frequency magnetic field in an examination zone of the magnetic resonance examination apparatus,
- a receiving coil system for receiving spin resonance signals generated in the examination zone of the apparatus,
- a transmitter arranged in close vicinity to the receiving coil system and connected thereto for the wireless transmission to a receiver of high frequency signals derived from the spin resonance signals received by said receiving coil system,
- said receiver being remote from the examination zone,
- wherein the frequency of said high frequency signals is chosen to be significantly different from the frequency of the spin resonance signals or harmonics thereof, and
- a processing unit also remote from the examination zone and coupled to the receiver for processing the high frequency signals received by the receiver thereby to derive from said signals the spin resonance signals.
