摘要： A radio frequency antenna comprising a resonant pickup circuit (102) arranged to pick up a magnetic resonance signal, an analog-to-digital converter (105) arranged to convert the magnetic resonance signal to digital data, and a frequency converter arranged to convert a primary band of frequencies of the digital data. By upshifting the frequency of the transmitted bit-stream, it is possible to RF-trap the transmission channel (109) by simple high-pass filtering techniques. In case the transmitted bit pattern has frequency components that approach the resonance frequency, an encoding technique like Manchester encoding can be used to eliminate unwanted signals.

摘要： It is proposed herein to improve the specifications of a low-noise amplifier (LNA) by integrating it in a chip. In order to cover a range of operating frequencies using a single chip, the integrated-circuit amplifier proposed herein comprises an input port configured to receive a magnetic resonance (MR) signal from a radio-frequency (RF) coil, one or more LNAs configured to amplify the received MR signal, and an output port configured to output the amplified MR signal from the one or more LNAs. The operating frequency of the RF coil depends on the field strength, The matching circuit, if present, needs to be tuned to operate at the operating frequency of the RF coil, and depends on the component values in the loop, thus on loop size. In contrast, the proposed integrated-circuit amplifier is capable of directly connecting to RF coils with different loop sizes, without the need for a matching circuit.
