3D thermoacoustic imaging based on compressive sensing

This work reports our recent progress in 3D thermoacoustic imaging based on compressive sensing. Thermoacoustic imaging has been extensively research in the past 15 years and has developed numerous applications especially in biomedical engineering. Pursuing a fast data measurement in the experimental process of thermoacoustic imaging is very meaningful. Compressive sensing based 3D thermoacoustic imaging technique holds great promise to achieve this goal. Detailed procedure of the novel method is introduced. Simulation results show that only 10 measurements are enough to obtain a good thermoacoustic image of four spherical objects.
