Description of Invention:
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.
