Abstract: A device for switching a connection relationship between an input channel and an output channel group determined according to a selection mode, a magnetic resonance imaging (MRI) apparatus including the switching device, and a method for controlling the MRI apparatus are disclosed. The device includes: a plurality of input channels capable of being respectively connected to a plurality of coils, each of which receives a radio frequency (RF) signal from a target object to which a magnetic field is applied; a plurality of output channels capable of being connected to an image processor designed to generate a magnetic resonance image on the basis of the received RF signal; and a switching portion configured to switch a connection relationship between the plurality of input channels and the plurality of output channels. If a first mode or a second mode is selected, the switching portion performs switching so that a first output channel group including the plurality of output channels outputs, or so that a second output channel group including predetermined parts from among the plurality of output channels outputs, the RF signal.

Abstract: A phased array RF coil module and an imaging apparatus using the same can receive a magnetic resonance signal generated from a target object at high receive sensitivity and improve a signal to noise ratio. The phased array RF coil module includes at least one first phased array RF coil unit generating a magnetic field having a component horizontal with the surface of a target object and a second phased array RF coil unit formed horizontally with the surface of the target object and generating a magnetic field having a component vertical to the surface of the target object. The imaging apparatus using the phased array RF coil module is a magnetic resonance imaging apparatus.
