摘要： Various methods and systems are provided for a disconnecting a receive coil from a transmit coil of a magnetic resonance (MR) imaging apparatus during a transmit operation. In one example, a device may include a first device and a second device, each having a first terminal and a second terminal operably coupling different terminals of a radio frequency (RF) coil with one or more data acquisition elements, each device including a pair of switches. In this way, by simultaneously operating each of switches of the devices, the receive coil may be isolated from a transmit RF coil during transmit operation.

摘要： Various methods and systems are provided for a disconnecting a receive coil from a transmit coil of a magnetic resonance (MR) system during a transmit operation. In one example, a cabling system may include a first line of coil-interfacing cable having a first set of hybrid switches, the first set of hybrid switches including a first switch, a first resonance circuit, and a second switch connected in series, and a second line of the coil-interfacing cable having a second set of hybrid switches, the first line and the second line of the coil-interfacing cable operably coupling one or more radio frequency (RF) coil elements to respective channels of the MR system. By positioning the first and the second sets of hybrid switches along different locations along the coil-interfacing cables, and simultaneously operating each set of hybrid switches, common mode currents may be interrupted along the coil-interfacing cables.
