The coil system includes a local volume coil configured to transmit and receive MRI signals and an array of surface coils configured to receive MRI signals.
Claims20
A coil system for magnetic resonance imaging (MRI), said coil system comprising:
- a local volume coil configured to transmit and receive MRI signals;
- and
- an array of surface coils configured to receive MRI signals.
A control system for a magnetic resonance imaging (MRI) system, said control system comprising:
- a first switching member configured to control transmit and receive operations of a local volume coil and an array of surface coils of the MRI system during a scan mode of operation;
- and
- a second switching member configured to switch between the scan mode of operation and a calibration mode of operation.
A magnetic resonance imaging (MRI) system comprising:
- a surface coil array;
- a local volume coil;
- and
- a controller configured to control operation of the surface coil array and local volume coil in each of a calibration mode and scan mode, wherein the controller provides (i) in the calibration mode for both transmitting and receiving by the local volume coil to acquire calibration information and (ii) in the scan mode for transmitting by the local volume coil and receiving by the surface coil array to acquire images of an object.
A method for controlling coils in a magnetic resonance imaging (MRI) system, said method comprising:
- providing a local volume coil and an array of surface coils;
- configuring the local volume coil to transmit and receive in a calibration mode of operation;
- and
- configuring the local volume coil to transmit and the array of surface coils to receive during a scan mode of operation.
