Recently, an electroacoustic imaging apparatus and two electroacoustic imaging methods have been developed. The two methods are "forward" and "reverse" electroacoustic imaging which requires the application of a probing signal, and the detection and measurement of an induced signal to produce images. The electroacoustic apparatus offers the advantage of generating 2D and 3D images non-invasively. It can simultaneously image several contrast mechanisms, including the Hall effect, the thermoacoustic effect, and the electroacoustic effect. Although this device uses a Piezoelectric transducer, fiberoptic acoustic sensors can also be substituted to take advantage of advances in acoustic wave detection technology.
