  • Circuit arrangement for generating rf signals for MR examinations
    Patent number: 5004983
    Abstract: The invention relates to a circuit arrangement for generating rf signals for MR examinations, comprising a read-only memory in which a signal is stored in the form of a series of data words, an address generator for reading data words from the read-only memory with a clock frequency, and a digital-to-analog converter which succeeds the read-only memory. In order to reduce the required storage capacity, a sinusoidal signal in the form of a series of data words is stored in the memory.

  • Magnetic resonance spectrometer
    Patent number: 4873486
    Abstract: A magnetic resonance spectrometer in which, at least in the receiving branch, the received spin resonance signal is transposed by successive mixing processes into a transposed signal having a higher frequency range than the baseband. The transposed signal is converted into a digital signal by an analog-to-digital converter.
