Abstract
A hybrid antenna array for use in an MRI device, the array comprising a plurality of loop-line elements, each loop line element comprising a loop element and a line element, wherein the loop element and the line element are aligned along their respective center axis and coupled at an input coil port; and wherein the plurality of loop-line elements are configured to operate in a multi-channel array.
Claims26
A hybrid antenna array for use in acquiring data using an MRI device, the antenna array comprising:
- one or more loop-line structures, each loop-line structure comprising a loop element and a line element which together form a hybrid transceiver block, wherein the loop element and the line element are aligned along their respective center axes, and wherein an input coil port includes at least one of a matching capacitor or an inductor for at least one of the elements of the block.
A hybrid antenna array for use in acquiring data using an MRI device, the hybrid antenna array comprising:
- a loop-coil element, the loop-coil element having a plurality of tuning capacitors;
- and
- a dipole antenna element,
- wherein the loop-coil element and the dipole antenna element combine to form a hybrid transceiver block,
- wherein the loop-coil element and the dipole antenna element are aligned along their respective center axes, and
- wherein at least one of the loop-coil element and the dipole antenna element further includes at least one of a matching capacitor or an inductor.
A method of using a hybrid antenna array, the method comprising the step of:
- using the hybrid antenna array in an MRI device to acquire at least one of functional data, spectroscopic data, and imaging data, the hybrid antenna array comprising:
- one or more loop-line structures, each loop-line structure comprising a loop element and a line element which together form a hybrid transceiver block, wherein the loop element and the line element are aligned along their respective center axes, and
- wherein at least one of the loop element and the line element further includes at least one of a matching capacitor or an inductor.
