Photoacoustic Characterization of Human Skin Phantom with Superficial Anomalies:Preliminary Results

摘要

Pulsed photoacoustic characterization of a human skin phantom with superficialanomalies has been done with a homemade sensor. The sensor was done with a PVDF film andwas used in the backward detection mode. The phantoms were agar gelatin slabs with thethickness of 100 mm and superficial anomalies were simulated by plastic spheres immersed inthe slabs. The sensitivity and resolution of the sensor to measure buried anomalies it is reported.
