Abstract
An apparatus for imaging includes: a radio frequency (RF) coil array having a first RF coil and at least one additional RF coil, where the RF coil array is adapted to generate an image signal; a preamplifier having an input impedance, where the preamplifier is adapted to receive the image signal from the first RF coil; and a transformer to couple the first RF coil to the preamplifier, where impedance of the transformer is adapted to match the input impedance of the preamplifier.
Claims20
An apparatus for imaging, comprising:
- a radio frequency (RF) coil array comprising a first RF coil and at least one additional RF coil, the RF coil array adapted to generate an image signal;
- a preamplifier having an input impedance, the preamplifier adapted to receive the image signal from the first RF coil;
- and
- a first transformer to couple the first RF coil to the preamplifier, impedance of the first transformer to match the input impedance of the preamplifier.
A method for imaging, comprising:
- obtaining an image with a radio frequency (RF) coil array comprising a first RF coil and at least one additional RF coil, the first RF coil providing an image signal;
- passing the image signal from the first RF coil through a first transformer to obtain a transformed signal;
- matching impedance of the first transformer to an input impedance of a preamplifier;
- and
- amplifying the transformed signal with the preamplifier.
An apparatus for imaging, comprising:
- a radio frequency (RF) coil array comprising a plurality of RF coils, the RF coil array adapted to generate an image signal, the RF coils being inductively decoupled from each other;
- and
- a plurality of preamplifiers, each preamplifier adapted to receive the image signal from a respective RF coil, a ground for each preamplifier being electrically isolated from a ground for each respective RF coil.
