  • Patent number: 10488451
    Abstract: A method for operating an inductive conductivity measuring device that has a transmitting coil with an input and a receiving coil, the transmitting coil and the receiving coil being inductively coupled to one another by an electrically conductive medium. An electrical preset alternating signal is generated and fed to the input of the transmitting coil. The method for operating an inductive conductivity measuring device is improved in that a frequency of a preset alternating signal is varied in a frequency interval, in the frequency interval, a frequency-dependent minimum input impedance at the input of the transmitting coil is determined using a response alternating signal, a minimum frequency of the response alternating signal is determined at the minimum input impedance at the input of the transmitting coil, and a conductivity of the medium is determined using the minimum frequency of the response alternating signal.

  • Patent number: 10481235
    Abstract: A magnetic resonance imaging apparatus according to an embodiment includes sequence control circuitry and processing circuitry. The sequence control circuitry conducts, on a subject, first imaging and second imaging that is subsequent to the first imaging. The processing circuitry estimates, based on a magnetic resonance image related to the first imaging and an imaging condition set with regard to the second imaging, information about an image quality in a case in which the second imaging is conducted. The processing circuitry presents, on a display, an estimation result, superimposing the estimation result on the magnetic resonance image. The processing circuitry receives a designation operation on the magnetic resonance image from an operator, and changes a setting of the imaging condition related to the second imaging based on the designation operation.

  • Patent number: 10473602
    Abstract: Various embodiments include a method for configuring and generating a non-adiabatic saturation pulse for use in nuclear magnetic resonance (NMR) logging. One such method configures the pulse by adjusting one or more of pulse amplitude modulation or phase cycling. The modified pulse is transmitted into a fluid such that a substantially uniform nuclear spin saturation or nuclear spin inversion echo response is received from the fluid. A wait time between the pulse transmission and the echo response that indicates that spin equilibrium has been achieved is substantially equal to a T1 time. The wait time is an indication of the characteristics of the fluid.
