A fully autonomous system for sequence detection and gradient measurement

Motivation: The threshold to efficient use of field cameras is high and they could benefit from being less dependent on the scanner system they're being used in. Goal(s): The aim of this work is to develop an independent field monitoring system that can synchronize itself with and make targeted measurements of MR sequences. Approach: We employ a commercial NMR field probe system and trigger it externally using a host PC for data processing and an FPGA as a timing system. Results: We are able to independently synchronize the monitoring system, make targeted measurements of a sequence and decompose a set of gradient waveforms. Impact: This work is a step towards enabling scanner independent monitoring of MR sequences with NMR field probes. This could be useful in cases where the integration of a field camera is not an option.
