Abstract
The present document describes methods and systems for exciting magnetic resonance in a sample using trains of pulsed, oscillating magnetic fields that are modulated in their phase and amplitude according to a source waveform derived from the known or estimated magnetic response of a sample. Also disclosed are methods and systems for acquiring a response signal from the sample wherein data acquisition events are synchronized or interleaved with said modulated pulse trains. Further disclosed are methods and systems for identifying one or more of the presence, absence, amount, and concentration of a target substance in a sample. Also disclosed is a magnetic resonance device which uses such pulse trains and synchronized acquisition to improve the selectivity of magnetic resonance data.
