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.
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.
