Abstract

In this work we present an improved solution for cardiac gating and ventilation timing in in vivo spectroscopic and imaging experiments. This approach makes use of a pulse conditioner to extract primary timing signals from noisy and fluctuating input signals. A timing controller is then used to set all additional timing outputs. Full feedback control is utilized in this timing controller to optimize both magnetic resonance and respiratory timing. Feedback control also helps ensure that timing errors will not occur during acquisition.
