A multi-center evaluation of a Pilot Tone-based triggering technique using the BioMatrix Beat Sensor has been performed in healthy volunteers and patients undergoing a cardiac MRI examination. At five different sites, and two different field strengths, a wide range of MR sequences typically used in standard cardiac MRI examinations were successfully triggered using the prototype Beat Sensor Cardiac triggering technology. By including a short signal training and RF calibration step at the start of the examination, the device proved robust across a range of subjects, thereby offering an alternative means to trigger cardiac examinations without the need to attach electrodes.
