Magnetic Resonance Imaging (MR Imaging) is routinely employed in diagnosing Alzheimer's Disease (AD), which accounts for up to 60–80% of dementia cases. However, it is time-consuming, and protocol optimization to accelerate MR Imaging requires loca

A coupler is an indispensable component to sample the forward and reflected power for the real-time radio frequency (RF) power monitoring system. The directivity of a coupler is a critical factor to achieve accurate RF power measurements. This paper

This work presents the feasibility demonstration of an automatic RF leakage canceler for magnetic resonance imaging (MRI) applications that require a simultaneous transmit and receive (STAR) system. The automatic system with wireless control enables
