Abstract

In this work photoacoustic imaging (PAI) based on multi element linear-array transducer, combined with multichannel collecting system was used for in vivo imaging of microcirculation of the human forearm. The Vevo® 2100 LAZR PAT system (VISUALSONICS) was used for imaging which simultaneously collects high-resolution ultrasound and photoacoustic signals. 3D PA and high frequency ultrasound scans, measured 30.5 mm (length) x 14.1 mm (width) x 10 mm (depth) were acquired from the area of forearm skin using 40 MHz frequency transducer at 860 nm wavelength. 3D structural and functional (microcirculation) maps of the forearm skin were obtained. The multi element linear-array transducer based PAI has been found promising in terms of resolution, imaging depth and imaging speed for in vivo microcirculation imaging within human skin.
