A gating and triggering system dedicated to nuclear magnetic resonance studies of isolated perfused heart.

Primary tabs

Goudemant, Jean-François [UCL] Lamalle, L Mottet, I. Demeure, R.

This work reports a low-cost and versatile electronic device designed to trigger NMR acquisitions from the cardiac cycle of an isolated perfused heart, or to perform electrical stimulation of the heart. The triggering is synchronised with the pressure curve of the perfused heart. The cardiac pacing is achieved from pulses of the NMR system, or by an internal pulse generator, in order to be operated separately from the NMR instrument.
