  • Nuclear magnetic resonance tomography apparatus with pre-polarization
    Patent number: 5936404
    Abstract: In a nuclear magnetic resonance tomography apparatus wherein imaging is implemented with hyperpolarized gases, a first magnet system having a high field strength for the pre-polarization of the nuclear spins is provided. A gradient system for generating magnetic field gradients and a radio-frequency arrangement for the excitation of nuclear spins in a subject as well as for the read-out of the arising nuclear magnetic resonance signals are provided in a second magnet system having lower field strength.
