Abstract: A magnetic resonance imaging system includes a lower body which has a flat upper surface, and contains a first magnetic pole, an upper body which has a lower surface disposed in opposed relation to the upper surface of the lower body, and contains a second magnetic pole, a bed disposed adjacent to the lower body, and a pair of support posts which are provided respectively on right and left sides of the lower body, and interconnect the lower body and the upper body. A space, formed between the lower surface of the upper body and the upper surface of the lower body, is open at least toward the bed between the pair of right and left support posts.
