Abstract
A magnetic resonance imaging apparatus according to an embodiment includes a receiver array coil structured with a plurality of receiver coils. Each of the receiver coils included in the receiver array coil includes a coil element, a first tuning element configured to tune a tunable frequency of the receiver coil to a desired frequency, and a series circuit including a switching element and a second tuning element and being connected in parallel with the first tuning element. The switching element is configured to disconnect the first tuning element and the second tuning element from each other at the time of transmitting and is configured to arrange the first tuning element and the second tuning element to be electrically conductive with each other at the time of receiving. At least two receiver coils positioned adjacent to each other among the plurality of receiver coils are decoupled from each other.
