Abstract :
This paper presents the design, implementation, and nuclear magnetic resonance (NMR) measurements of a wireless, magnetic compliant, implant that increases the signal sensitivity of NMR images by 3.8dB and 2.6dB in 4.7T and 11.1T magnetic field strengths respectively. The device supports sustained reliable operation through a strongly coupled resonance wireless powering scheme in addition to improving high-resolution image SNR up to 73% within the region of interest.
