Abstract

In most clinical magnetic resonance imaging systems, only commercial receive coils with the appropriate connector and encoding can be plugged in. When willing to use a dedicated receive coil for a specific study which cannot be achieved with commercial coils, the researcher faces the connecting issue related to the specificity of the proprietary connector. In this work, a universal device is proposed which allows for the connection of any single channel dedicated coil on any magnetic resonance (MR) system, as long as it is provided with at least one commercial receive coil. Technical feasibility of the universal connecting device was demonstrated on a 3 T MR clinical imager. The device included an independent active decoupling circuit while signal transmission to the data cabinet was achieved by electromagnetic coupling with a commercial receive coil plugged to the MR device. The universal connecting device was notably characterized in terms of signal-to-noise ratio (SNR) and compared to the standard connection. Image SNR was comparable using both means of connection. © 2015 Wiley Periodicals, Inc. Concepts Magn Reson Part B (Magn Reson Engineering) 45B: 125–133, 2015

通用射频接收线圈连接器:概念和验证在3t

在大多数临床磁共振成像系统中，只有带有适当连接器和编码的商业接收线圈才能插入。当愿意使用专用接收线圈进行商业线圈无法实现的特定研究时，研究人员面临与专有连接器的特异性相关的连接问题。在这项工作中，提出了一种通用装置，它允许在任何磁共振(MR)系统上连接任何单通道专用线圈，只要它提供至少一个商业接收线圈。在3t磁共振临床成像仪上验证了通用连接装置的技术可行性。该设备包括一个独立的有源去耦电路，而信号传输到数据柜是通过电磁耦合与插入到MR设备的商业接收线圈实现的。与标准连接相比，通用连接装置在信噪比(SNR)方面具有显著的特点。两种连接方法的图像信噪比具有可比性。©2015 Wiley期刊公司机械工程B辑(机械工程学报)，45 (1):125-133,2015

期刊介绍： Concepts in Magnetic Resonance Part B brings together engineers and physicists involved in the design and development of hardware and software employed in magnetic resonance techniques. The journal welcomes contributions predominantly from the fields of magnetic resonance imaging (MRI), nuclear magnetic resonance (NMR), and electron paramagnetic resonance (EPR), but also encourages submissions relating to less common magnetic resonance imaging and analytical methods. Contributors come from both academia and industry, to report the latest advancements in the development of instrumentation and computer programming to underpin medical, non-medical, and analytical magnetic resonance techniques.
