Title:
磁気共鳴イメージング装置及びＲＦコイル装置
Document Type and Number:
Japanese Patent JP6611597
Kind Code:
B2
Abstract:
According to one embodiment, magnetic resonance imaging apparatus includes a transmission coil, a plurality of reception channels, transmission/reception circuitry, and processing circuitry. The transmission coil transmits an RF wave to a subject. The reception channels receive MR signals generated from the subject. The transmission/reception circuitry controls the transmission coil to change the flip angle of a nucleus contained in the subject and excited by the transmitted RF wave. The processing circuitry determines whether the reception channels include an impaired channel, based on the comparison between the distributions of the signal values of the received MR signals with respect to the changing flip angles among the reception channels.
