Thermoacoustic imaging Thermoacoustic computed tomography is an hybrid imaging technique that converts incident electromagnetic energy into sound waves that can be used to reconstruct the absorption pattern of the incident energy source in 3D with excellent spatial resolution as good as 10 microns . Imasonic detector arrays have been engineered specifically to optimise thermoacoustic signal detection and have been found to offer a fourfold improvement in detection sensitivity compared with conventional piezoelectric transducers:
