Paper Abstract
Photoacoustic tomography is a potential and noninvasive medical imaging technology. It combines the advantages of
pure optic imaging and pure ultrasound imaging. We have explored photoacoustic imaging with different filters, such as
RL, SL, Modi-SL arid Kwoh-Reed, which take important roles on reconstructed images. The results of simulations and
experiments show that the filter of Kwoh-Reed can restrain noise effectively and improve the contrast of images
compares with the filters of RL, SL, ModiSL in the presence of strong noise. A Q-switched Nd:YAG laser operating at
532nm was used as light source. The laser had a pulse width of 7ns and a repetition frequency of 30Hz. A needle PVDF
hydrophone with diameter of I mm was used to detect photoacoustic signals.
