摘要： This document discusses, among other things, a system and method for a coil having a plurality of resonant elements capable of radiofrequency transmission, reception, or both transmission and reception. One example includes a receive-only coil disposed within a transmit-only coil. Adjacent resonant elements are decoupled from one another by both capacitive elements and by the geometric configuration of the elements. Cables are coupled to each resonant element and are gathered at a junction in a particular manner.

摘要： Apparatus and method that are more efficient and flexible, and obtain and connect high-power RF transmit signals (TX) to RF-coil devices in an MR machine or other devices and simultaneously receive signals (RX) and separate net receive signals NRX) of interest by subtracting or filtering to remove the subtractable portion of the transmit signal (STX) from the RX and preamplifying the NRX and signal processing the preamplified NRX. In some embodiments, signal processing further removes artifacts of the transmitted signal, e.g., by digitizing the NRX signal, storing the digitized NRX signal in a memory, and performing digital signal processing. In some embodiments, the present invention also includes pre-distorting the TX signals in order to be better able to identify and/or remove the remaining artifacts of the transmitted signal from the NRX signal. This solution also applies to other high-power RF-transmit-antennae signals.
