ABSTRACT:
An MR imaging system comprises a first gradient coil unit(first G coil unit) for providing magnetic gradients superimposed in a static magnetic field, a first RF coil unit for transmitting an RF pulse to a patient and receiving a MR signal from the patient, a second gradient coil unit(second G coil unit) and a second RF coil unit. The second G coil unit is located between the patient and the first G coil unit. In a first operating mode(for example, spin echo scan mode), the second G and RF coil units are moved out the first G coil unit and the first RF coil unit is moved into the first G coil unit by guiding these units along a rail or the second G and RF coil units are drawn out from the first G coil unit and the first RF coil unit is inserted into the first G coil unit so that these units are located in predetermined position. A connection of a gradient power source to the first and second G coil unit and a connection of a duplexer to the first and second RF coil unit are switched so that the gradient power source is connected to the first G coil unit and the duplexer is connected to the first RF coil assembly. In a second operating mode (for example, echo planar scan mode), these units are located inversely and the connections are switched inversely. In one preferred embodiment, the second G coil unit and the first RF coil unit are integrated into an inner unit and these units are moved together by moving the inner unit.
