Abstract

Wireless radio frequency coils offer an alternative to conventional cable-connected coils due to their compatibility with multiple vendor MRI systems and reduced electromagnetic interaction with the environment of the MRI scanner. However, wireless coils being inductively coupled with a transceiver body coil require manual input power calibration due to the significant increase of a body coil transmit efficiency locally in the region of interest and disturbance of

homogeneity complicating routine scanning procedures. This study aims to implement the concept of a wireless receive-only coil for female breast MRI at 1.5T. The approach combines the advantages of wireless coils to increase signal to noise ratio of transceiver body coil in the target region of interest and the ability to perform the automatic reference voltage calibration.

用于1.5T MRI的体积无线接收线圈的概念

无线射频线圈是传统电缆连接线圈的另一种选择，因为它与多个供应商的MRI系统兼容，并且减少了与MRI扫描仪环境的电磁相互作用。然而，无线线圈与收发器本体线圈电感耦合需要手动输入功率校准，因为本体线圈在感兴趣区域的局部传输效率显着增加，并且B1+均匀性的干扰使常规扫描程序复杂化。本研究旨在实现女性乳房MRI 1.5T无线接收线圈的概念。该方法结合了无线线圈的优点，提高了收发器本体线圈在感兴趣区域的信噪比，并能够进行自动参考电压校准。

期刊介绍： The Journal of Magnetic Resonance presents original technical and scientific papers in all aspects of magnetic resonance, including nuclear magnetic resonance spectroscopy (NMR) of solids and liquids, electron spin/paramagnetic resonance (EPR), in vivo magnetic resonance imaging (MRI) and spectroscopy (MRS), nuclear quadrupole resonance (NQR) and magnetic resonance phenomena at nearly zero fields or in combination with optics. The Journal''s main aims include deepening the physical principles underlying all these spectroscopies, publishing significant theoretical and experimental results leading to spectral and spatial progress in these areas, and opening new MR-based applications in chemistry, biology and medicine. The Journal also seeks descriptions of novel apparatuses, new experimental protocols, and new procedures of data analysis and interpretation - including computational and quantum-mechanical methods - capable of advancing MR spectroscopy and imaging.
