Abstract
Systems, methods, and other embodiments associated with dynamically selectively configuring wireless transmitters associated with MRI detector coils are described. One example apparatus includes a detector coil to receive an NMR signal. The apparatus includes a dynamically configurable transmitter to transmit an RF transmission according to a configurable set of transmission parameters. The RF transmission is based on the NMR signal received by the MRI detector coil. The apparatus includes a tuning logic that cycles between an active state and a passive state under the control of a tuning program. While in the passive state, the tuning logic is to generate substantially no RF that could interfere with receiving the NMR signal at the MRI detector coil. While in the active state, the tuning logic is to configure the dynamically configurable transmitter to transmit according to the set of transmission parameters.
