Claims13
A phased-array knee coil for a Magnetic Resonance Imaging (MRI) system, the phased-array knee coil comprising:
- a transmit coil array;
- and
- a receive coil array having a plurality of coils configured to provide a first imaging mode and a second imaging mode and wherein the plurality coils each include a first coil element defining an inner coil loop and a second coil element defining an outer coil loop with the first coil element providing the first imaging mode and the second coil element providing the second imaging mode, the first imaging mode being a zoom imaging mode and the second imaging mode being a full imaging mode.
A phased-array knee coil for a Magnetic Resonance Imaging (MRI) system, the phased-array knee coil comprising:
- a transmit coil array including a birdcage coil;
- and
- a receive coil array including a plurality of lattice-shaped coil elements, each of the lattice-shaped coil elements including a plurality of coils configured to provide a first imaging mode and a second imaging mode, the first and second imaging modes user selectable to provide different imaging field-of-views and wherein each of the lattice-shaped coil elements comprises an inner coil element and an outer coil element, the inner coil element conflaured to provide the first imaging mode and the outer coil element configured to provide the second imaging mode, the first imaging mode being a zoom imaging mode and the second imaging mode being a full imaging mode.
A method of providing a phased-array knee coil for a Magnetic Resonance Imaging (MRI) system, the method comprising:
- providing a transmit coil array;
- and
- configuring a receive coil array having a plurality of coils to provide imaging operation in each of a first imaging mode and a second imaging mode, and in combination with the transmit coil array providing different fields-of-view for imaging in each of the first and second imaging modes and;
- configuring the plurality of coils as an inner coil loop and an outer coil loop, the inner coil loop providing the first imaging mode and the outer coil loop providing the second imaging mode, and wherein the first imaging mode is a zoom imaging mode and the second imaging mode is a full imaging mode.
