Abstract: According to one embodiment, a magnetic resonance imaging apparatus includes processing circuitry and sequence control circuitry. The processing circuitry specifies a position of an imaging target of a subject in a bore, using an image collected by a first imaging protocol. The processing circuitry determines, in accordance with the specified position, a correction value for a phase of an RF pulse and/or a correction value for an amplitude of the RF pulse, the RF pulse being related to a transmit RF wave, so that non-uniformity in a magnetic field of the transmit RF wave transmitted to the imaging target can be corrected. The sequence control circuitry executes a second imaging protocol for the subject, using the determined correction value.

Abstract: Example implementations described herein are directed to detection of historical anomalous events that are similar to currently occurring events in a transmission power system based on phasor management unit (PMU) data to provide information to grid operators with online decision support. From the high-resolution time synchronized PMU data, the historical events can be quickly retrieved and compared to the currently occurring event so that operators can be provided with remedy actions that were attempted in response to the historical events. Utilization of PMU information for such decision support may compliment operation practices relying on supervisory control and data acquisition (SCADA) measurements by allowing a much fast response to the currently occurring event. Accurate identification of similar, historical events can advise grid operators of the cause of disturbances and provide ideas for response.
