Real-time monitoring of deep-tissue electric field distribution during electroporation therapy remains a significant clinical challenge. Electroacoustic Tomography (EAT) addresses this need by detecting ultrasound waves generated during pulsed electric energy induces cell membrane poration. Using a three-dimensional matrix array transducer, we demonstrate EAT's capability to visualize volumetric electric field distributions in real-time. A comprehensive database of EA signals was developed using square pulses ranging from 600-1000V with pulse widths of 60-150ns. To validate the 4D imaging capabilities, discrete pulse trains were delivered from 50 to 1000V at 50V increments, with universal back projection reconstructions effectively visualizing the source pressure distribution. Dynamic reconstructions clearly de monstrate electric field strength growth correlating with voltage increments. Our system's clinical viability has been validated through both in vivo murine studies using stable ablation energy and in vitro vegetable model experiments. Three-dimensional correlation between ablated regions and imaging intensity across multiple depths yielded structural similarity index (SSIM) values greater than 0.85, confirming EAT's ability to provide accurate dose maps. This work represents the first volumetric reconstruction of experimental electroporation using a planar ultrasound transducer system, establishing EAT as a viable deep-tissue monitoring modality for thera
