Abstract
According to one embodiment, a magnetic resonance imaging apparatus includes a static field magnet, a gradient coil, at least one radio frequency coil, a receiver and processing circuitry. The static field magnet, the gradient coil, the at least one radio frequency coil and the receiver are configured to acquire magnetic resonance signals from an object. The processing circuitry is configured to generate magnetic resonance image data based on the magnetic resonance signals. The receiver is configured to convert analog magnetic resonance signals received by the at least one radio frequency coil into digital magnetic resonance signals without a downconversion; separate the digital magnetic resonance signals into in-phase signals and quadrature-phase signals; and perform filter processing for removing noises of the in-phase signals and the quadrature-phase signals.
