Russell Witte, a University of Arizona professor of medical imaging who holds a joint appointment in biomedical engineering, has co-founded the startup ElectroSonix LLC to commercialize a novel cardiac imaging method.
Acoustoelectric cardiac imaging, or ACI, externally emits ultrasound waves that interreact with the heart’s electrical currents to produce a map of electrical activity. This noninvasive imaging technique allows physicians to acquire precise, real-time data before, during and after a cardiac ablation procedure to destroy tissue causing abnormal heart rhythms.
UA BME doctoral student Alexander Alvarez has been helping Witte perfect the imaging system since 2017. He now works as an engineer for the company.
