摘要： In a method and magnetic resonance (MR apparatus for reducing aliasing artifacts in the imaging for MR-monitored high intensity focused ultrasound HIFU therapy, a primary coil is used to receive the MR signals, and an additional coil is provided to receive interfering MR signals that form aliasing artifacts in the MR-monitored HIFU therapy imaging. The MR signals received by the primary coil and the interfering MR signals received by the additional coil are concurrently acquired. The interfering MR signals received by the additional coil are removed from the MR signals received by the primary coil. MR images are generated based on the MR signals with the interfering MR signals removed. Aliasing artifacts caused by the interfering MR signals thus are removed from the MR images without reducing the resolution of the scanned body parts in the MR images. In addition, the MR scanning time can be—maintained by using a proper phase oversampling technology in the concurrent signal acquisition.

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.
