Paper Abstract

We report on experimental demonstration of focused photoacoustic (PA) imaging for simultaneous recovery of the acoustic and optical properties of absorber in homogeneous media. The PA signals are reconstructed from tissue-like phantom experiments using Hilbert transform (HT) algorithm coupled with a focused PA imaging system. The results demonstrate that the HT-based PA signal occurs at the edge of heterogeneous sample. The average acoustic velocity could be obtained by the size dividing the traveling time. In addition, the absorption coefficient of absorber could be reconstructed by the intensity of the HT-based PA signal at the edge of sample based on the theoretical analysis.
