Abstract: A radio frequency coil according to an embodiment is configured to receive a magnetic resonance signal from an examined subject. The radio frequency coil includes an expandable and contractible first element and an expandable and contractible second element. The radio frequency coil has an overlap region where a first loop formed by the first element overlaps with a second loop formed by the second element. The ratio of the area of the overlap region to the area of the region enclosed by the first loop changes in accordance with expansion/contraction of the first element forming the first loop. The first element and the second element include liquid metal in at least a part thereof.
