The ACORYS MAPPING SYSTEM  is a non-invasive electrocardiographic imaging (ECGI) system for the beat-to-beat, multi-chamber and three-dimensional mapping of cardiac activity. ACORYS combines hardware (a biopotential amplifier and a high-density sensor vest) together with innovative image and signal processing technologies to provide the clinicians with cardiac electroanatomic maps, unmasking electrical activity in the surface of the heart in a completely non-invasive way.
