    摘要: A rotation positioning device for a coil of a magnetic resonance imaging apparatus, having a cavity in the coil for accommodating a part to be examined, has a backing member that can freely rotate within this accommodating cavity. The backing member is provided with a first driving member and a first rotating member, and the coil is provided with a second driving member and a second rotating member. The first driving member and the second driving member form a transmission pair, and the first rotating member can rotate relative to the second rotating member under the drive of the first driving member and the second driving member. The second driving member can be driven manually or by an external driving source connected thereto to drive the first driving member, thereby driving the backing member to rotate via the cooperation of the first rotating member and the second rotating member. Also, by appropriate configuration of parameters, such as position and size, of the first driving member and the second driving member, the rotation angle or range of the backing member can be controlled precisely and quantitatively.

    摘要: In a signal receiving method and device for a magnetic resonance imaging system, a first loop receiver coil has a saddle receiver coil overlapped thereon, and two individual loop receiver coils or two counter rotating loop receiver coils connected end-to-end are equally spaced from the first loop receiver coil along the axial direction of the first loop receiver coil, forming a dual-loop receiver coil unit. Thus, the magnetic resonance signal generated by human tissue induces current on the dual-loop receiver coil unit following excitation of the signal. When the device is operated, the signal current induced in the saddle receiver coil, the first loop receiver coil and the dual-loop receiver coil unit respectively are added, thus increasing the output signal-to-noise ratio, improving the edge imaging effect, increasing the coverage of the coil signal and improving the signal homogeneity in the imaging area.

    摘要: A method includes generating emitted signals using transmitter elements and measuring received signals using receiver elements. The received signals are reflected portions of the emitted signals and the received signals correspond to one or more targets. The method also includes applying a first matched filter to the received signals to determine range information for the received signals, filtering the received signals based on the range information to define filtered signals, and determining calibration parameters using the filtered signals. The method also includes correcting the received signals using the calibration parameters to define calibrated signals and determining angle of arrival information for the received signals using the calibrated signals.
