摘要:
A magnetic resonance system has a patient receptacle and a base body. The patient receptacle has a subframe and a patient bed supported thereon so as to move a patient thereon through the base body. The base body has a basic field magnet system, a gradient system and an RF system that are operable to obtain an analog magnetic resonance signal from the patient. The patient receptacle has a signal conversion device composed of an A/D converter, a modulator, and a transmitter. The base body has a signal conversion device composed of a receiver and a demodulator. The A/D converter receives the magnetic resonance signal and digitizes it. The modulator modulates a carrier signal with the digitized magnetic resonance signal. The transmitter transmits the modulated carrier signal via an air gap to the receive. The receiver receives the transmitted carrier signal. The demodulator extracts the digitized magnetic resonance signal from the received carrier signal by demodulation and supplies it to an evaluation device for continuing evaluation.
