MAGNETIC RESONANCE IMAGING SYSTEM HAVING PROBES FOR FIELD INVESTIGATION Russian patent published in 2020 - IPC G01R33/389 

FIELD: physics.

SUBSTANCE: using: for magnetic resonance imaging. Essence of the invention consists in the fact that the system of magnetic-resonance investigations contains system of probes for investigation of the field for measurement of magnetic field distribution from the main magnetic field and from the gradient magnetic field. Measurements are performed in earlier configuration and resultant magnetic field caused by gradient switching or external causes. Response relationship is output from the measured resultant magnetic field and stored in memory. Response relationship from memory is available to compensate for activation of gradient fields or correction during reconstruction for response ratio during reconstruction. This compensation or correction can be performed in current configuration.

EFFECT: technical result is providing a system of probes for field investigation, which is less dependent on space available for placement of probes for field investigation.
