Patent ID: 8704522

Claim:
A magnetic resonance imaging apparatus comprising: a first clock generator which generates a first clock signal; a pulse generator which generates an excitation pulse signal based on the first clock signal; a transmission coil which wirelessly transmits an excitation pulse based on the excitation pulse signal; a reception coil which receives the excitation pulse wirelessly transmitted from the transmission coil and a magnetic resonance echo emitted from a subject by a function of the excitation pulse to obtain a radio frequency signal; a second clock generator which generates a second clock signal; a digital converter which digitizes, synchronously with the second clock signal, the radio frequency signal or signal obtained by subjecting the radio frequency signal to predetermined processing, to obtain radio frequency data; a pulse detector which detects excitation pulse data corresponding to the excitation pulse from the radio frequency data; a phase detector which detects a phase of a pulse indicated by the excitation pulse data detected by the pulse detector; and a corrector which calculates an amount of a phase shift which occurs in the magnetic resonance echo indicated by the radio frequency data during the digitization in the digital converter, based on the excitation pulse data and the phase detected by the phase detector and which corrects the radio frequency data so as to compensate for the amount of the phase shift.
