Quantifying the Transmit‐Power Threshold for Reliable Passive Detuning of Inductively Coupled Wireless Resonators in MRI: A Phantom Study
ABSTRACT This work develops and validates a practical method for quantifying the transmit‐power threshold at which passive detuning of inductively coupled wireless resonators becomes reliable in MRI. All experiments were performed using phantoms. A near/far spatial signal ratio is computed from a series of gradient‐ech...
