  • Patent number: 10838101
    Abstract: An example method includes introducing a solution into at least part of a reservoir. The solution includes a contrast agent and a fluid. The contrast agent includes a polymer having a dielectric constant that may be greater than a predefined value. The example method also includes using at least one EM transmitter antenna to direct a first electromagnetic (EM) signal into the reservoir. The first EM signal passes through the at least part of the reservoir into which the solution was introduced. The first EM signal is received using at least one EM receiver antenna following passage through the at least part of the reservoir. Data is determined that represents a difference between a first travel time of the first EM signal transmitted through the contrast agent in the reservoir and a second travel time of a second EM signal transmitted through water-saturated reservoir rock. Information about a physical feature of the at least part of the reservoir is generated based on the data.

  • Patent number: 10823804
    Abstract: In a method and apparatus for capturing magnetic resonance data from an imaging volume of a patient in which liquid, such as particular blood, is moving, a bSSFP magnetic resonance sequence is executed in which nuclear spins located within the imaging volume are cyclically excited by radiation of a radio-frequency pulse, using a magnetic resonance scanner. A ramp pulse is used as the radio-frequency pulse, which establishes a flip angle of the spins that is spatially variable within the imaging volume. The flip angle is designed to be lower on a side or the imaging volume from which the liquid flows into the imaging volume than on the side at which the liquid flows out, and the flip angle increases monotonically.

  • Patent number: 10775459
    Abstract: The invention relates to compounds known as “optorelaxers,” for example, spin crossover (SCO) complexes that exhibit light-induced excited state spin trapping (LIESST) effects with transient unpaired electron spins, which are created (or destroyed) by varying the level and/or wavelength of light to which the complexes are exposed. Light conditions are used to switch the optorelaxers between transient paramagnetic and diamagnetic states to provide real-time control of T1 relaxation in nuclear magnetic resonance (NMR) spectroscopy methods. The optorelaxers and methods of the invention provide increased detection sensitivity of NMR spectroscopy, with increased structural information content, while maintaining resolution for a wide variety of different NMR-active nuclei.
