Fiber optic telemetry for switched-mode current-source amplifier in magnetic resonance imaging (MRI)

摘要

Example systems, apparatus, circuits, and other embodiments described herein concern acquiring telemetry data from an MR system and providing the telemetry data via fiber optic cable. One example apparatus includes a telemetry signal acquisition element (e.g., circuit, circuit component) that is configured to acquire a telemetry signal from a component in the MR apparatus. The component may be, for example, a transmit coil or an on-coil amplifier. The example apparatus also includes a fiber optic cable that is configured to carry an output signal from the MR apparatus through a field produced by the MR apparatus. The example apparatus also includes a telemetry signal output element that is configured to produce the output signal from the telemetry signal and to transmit the output signal via the fiber optic cable.
