Photoacoustic characterization of human skin phantom with superficial anomalies: Preliminary results

Pulsed photoacoustic characterization of a human skin phantom with superficial anomalies has been done with a homemade sensor. The sensor was done with a PVDF film and was used in the backward detection mode. The phantoms were agar gelatin slabs with the thickness of 100 mm and superficial anomalies were simulated by plastic spheres immersed in the slabs. The sensitivity and resolution of the sensor to measure buried anomalies it is reported. © 2008 American Institute of Physics
