Abstract Currently, human magnetic resonance (MR) examinations are becoming highly specialized with a pre-defined and often relatively small target in the body. Conventionally, clinical MR equipment is designed to be universal that compromises its efficiency for targets. Here, we present concept targeted imaging (MRI), which can directly integrated into existing systems, demonstrate feasibility breast imaging. The comprises spatial redistribution passive focusing of radiofrequency flux aid...
Dielectric resonators made of high permittivity materials with low losses have been extensively studied for application in magnetic resonance imaging (MRI) and spectroscopy. They can focus, redistribute, enhance the radio frequency field a controlled way. In this Letter, we investigate coupled very-high dielectric clinical bilateral breast MRI. The are tuned to support TE mode within 3 T MRI implemented as pair coaxial hollow cylinders consisting ceramic rings extremely (ε ∼ 870) loss. We...
In this paper, we present the initial experimental investigation of a two-coil receive/transmit design for small animals imaging at 7T MRI. The system uses butterfly-type coil tuned to 300 MHz scanning 1H nuclei and non-resonant loop antenna with metamaterial-inspired resonator ability tune over wide frequency range X-nuclei. 1H, 31P, 23Na 13C, which are particular interest in biomedical MRI, were selected as test work. Coil simulations show two parts radiofrequency (RF) assembly be...

Abstract We present the initial experimental results obtained using a two-part receive/transmit (Rx/Tx) radiofrequency (RF) coil design for small animals magnetic resonance imaging at 7 T. The assembly uses butterfly-type tuned to 300 MHz scanning 1 H nuclei and non-resonant antenna with metamaterial-inspired resonator tunable over wide frequency range X-nuclei. H, 31 P, 23 Na 13 C are selected as test in this work. Coil simulations show two parts of RF-assembly be efficiently operating...
Dielectric resonators based on high permittivity materials with low losses have recommended themselves as good candidates for improving magnetic resonance imaging (MRI) characteristics. Mainly due to the ability focus and enhance radiofrequency (RF) field, they are promising alternatives dedicated cable-connected RF coils. In this work, we investigate a system of coupled, very-high dielectric bilateral breast MRI at 3T. The implemented pair coaxial hollow cylinders consisting ceramic rings,...
