Impedance-Acoustic Tomography
In this work we present a new hybrid imaging technique that combines electrical impedance tomography (EIT) with acoustic tomography. The novel technique makes use of the fact that the absorbed electrical energy inside the body raises its temperature, thus leading to expansion effects. The expansion then induces an acoustic wave which can be recorded outside the body and consequently be used to calculate the absorbed energy inside the body, from which the electrical conductivity can be reconstructed. In other words, we try to combine the high contrast of EIT with the high resolution of ultrasound.
