| 英文摘要 | Mechanical property measurement of biological tissues is important for physiological and pathological studies. Photoacoustic (PA) methods have been a useful tool for mechanical property measurement with the advantages of optical contrast and noninvasive property. PA method uses the time information of PA signal to characterize viscoelasticity, which, however, is contradictory to depth measurement. In this work, echo signal in PA imaging system was utilized as an additional source making it possible to simultaneously measure viscoelasticity and depth. The average time and interval time of main and echo signals were used for viscoelasticity and depth measurement, respectively. Three gelatin samples with different mechanical properties at different depths were successfully distinguished by this method. The three-dimensional viscoelasticity measurement will further broaden applications in biological tissue research. |
