The present embodiments relate generally to medical care and more particularly to a new imaging modality referred to herein as electroacoustic tomography (EAT) that not only depicts electrical field energy distribution in real time, but also enables clear discrimination between IRE and RE zones in situ during the treatment. According to some aspects, EAT exploits the phenomenon that the amplitude of acoustic emission generated by an electric field is proportional to the electrical energy deposition in tissue. After detecting these acoustic waves with ultrasound transducers, an image of the electric field distribution can be reconstructed in real-time. This will allow real time monitoring the IRE and provides feedback control of the treatment. Some embodiments are directed to a novel EAT combined with ultrasound (EAT / US) guided IRE intervention that permits a) real time ultrasound image-guided needle placement, and b) intraoperational discrimination of IRE and RE zones during the treatment of cancer.
