  • System and method for hyperpolarizing a substance and quenching radicals therein
    Patent number: 10520561
    Abstract: A system for hyperpolarizing a substance is provided. The system includes a cryostat, a polarizer, and a shuttle. The cryostat is operative to generate radicals within the substance by exposing the substance to electromagnetic radiation. The polarizer is operative to hyperpolarize the substance via the radicals, and to quench the radicals within the substance by adjusting a temperature of the substance after the substance has been hyperpolarized. The shuttle is operative to transport the substance while maintaining hyperpolarization of the substance.
    Type: Grant
    Filed: September 27, 2017
    Date of Patent: December 31, 2019
    Assignees: GENERAL ELECTRIC COMPANY, MEMORIAL SLOAN KETTERING CANCER CENTER
    Inventors: Arnaud Comment, Albert P. Chen, Kayvan Rahimi Keshari

  • Optimized spectral-spatial pulse
    Patent number: 8035381
    Abstract: A computer implemented method for designing a spectral-spatial pulse for exciting at least one passband and minimally exciting at least one stopband is provided. A uniform shaped spectral envelope is generated. For a plurality of kz?0, kz dependent weights for a spectral envelope that approximate a kz=0 envelope and provides the at least one passband and the at least one stopband for each of the plurality of kz?0 is generated.
