Body Conformal Linear Ultrasound Array for Combined Ultrasound and Photoacoustic Imaging

We report on the development of combined ultrasound and photoacoustic imaging system using Lead Zirconate Titanate (PZT) based flexible bulk transducer arrays. The transducer was made with a new and simple technique and electronically interfaced with a research ultrasound system to obtain ultrasound image of custom targets. We also report for the first time, A-line photoacoustic signal from the flexible transducer array thereby laying the foundation of body conformal ultrasound co-registered photoacoustic imaging system.
