摘要:
A HIFU compatible receiving coil for MRI radio-frequency signals has an antenna and an amplifier connected to each other, each for receiving and amplifying MRI radio-frequency signals, and a filter positioned in front of the amplifier for filtering the HIFU low frequency signals received by the antenna at the same time as receiving the MRI radio-frequency signals. In a method for receiving the MRI radio-frequency signals and then for amplifying the same, the received MRI radio-frequency signals are filtered before being amplified, so as to filter out the HIFU signals received at the same time as the MRI radio-frequency signals. By this filtering, the HIFU signals among the HIFU signals and MRI radio-frequency signals simultaneously received by the antenna are filtered out at the same time as the HIFU treatment, and the remaining MRI radio-frequency signals are connected into the MRI system after being amplified by the amplifier for real-time imaging. Since the amplifier only processes the MRI radio-frequency signals, it can stay in a normal linear working status to ensure the normal proceeding of the subsequent real-time imaging.
