Magnetic resonance diagnosis apparatus, noise spatial distribution generation method, and signal acquisition method

摘要

A magnetic resonance diagnosis apparatus includes a coil assembly (100) including a high-frequency coil (107), a transmission unit (108T) which excites magnetization of a specific atomic nucleus of an object via the high-frequency coil, a reception unit (108R) including a detection unit (121) for receiving a magnetic resonance signal via the high-frequency coil, a low-pass filter (123), and an analog/digital converter (125), a control unit (106) which sets a passband of the low-pass filter to not less than three odd multiple of a frequency band determined from an imaging field of view, and sets a sampling frequency of the analog/digital converter to an oversampling frequency exceeding a signal band of the magnetic resonance signal, a noise spatial distribution generating unit (110) which generates a noise spatial distribution on the basis of an output from the reception unit.
