Analysis and improvement of thermoacoustic signals and image
In order to distinguish the microwave absorbability in deferent tissue from thermoacoustic image efficiently, the thermoacoustic signals excited by microwave were analyzed, and the shortage of image which built up by thermoacoustic signals directly was discussed. The method, which was used to improve the thermoacoustic signals, was realized by programming the Matlab program. The results show that the modified thermoacoustic signals and image can reflect the microwave absorbability of tissue very well and the boundaries between different tissues are very clear. Correspondingly, the probability of misjudge is obviously reduced.
