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 switch matrix, a switch matrix assembly, and a magnetic resonance imaging (MRI) apparatus are disclosed. The switch matrix includes a first path to which an electric signal is applied; a first switching unit configured to selectively and electrically interconnect a first input unit and a first end of the first path or to open the first end of the first path; and a second switching unit configured to selectively and electrically connect a second input unit to a second end of the first path or to open the second end of the first path.
Abstract:
A magnetic resonance imaging (MRI) device includes at least one switching cell that uses a first switcher to switch paths for two of four radio frequency (RF) signals is used to output the two RF signals. The MRI device includes RF coils including a plurality of coils for receiving RF signals from an object to which magnetic fields are applied; an image processor for creating a magnetic resonance image based on the received RF signals; and a switching unit for switching connections between a plurality of input ports connectable to the plurality of coils and a plurality of output ports connectable to the image processor, wherein the switching unit includes at least one switching cell including four input ports, two output ports connected to two of the four input ports, and a first switcher for switching between paths extended from second and third input ports among the four input ports.
