The magnetic resonance imaging apparatus includes: a calculation means for calculating the amount of absorption of electromagnetic waves into the object according to the emission of RF pulses in a part of the object or a bed position where imaging is scheduled； a means for setting imaging conditions, in which the calculated amount of absorption satisfies conditions of the specified value of the amount of absorption of electromagnetic waves, from the relationship between the calculated amount of absorption and the specified value of the amount of absorption of electromagnetic waves； and a bed control device that controls a top plate according to the set imaging conditions.
