Miniaturized transparent ultrasound sensor for photoacoustic endoscopy

Abstract

Photoacoustic endoscopy (PAE) promises to provide diagnosis information and treatment guidance in several clinical contexts. In this work, we developed a transparent ultrasound sensor based on a polyvinylidene fluoride thin film with indium tin oxide as electrodes. The sensor had a diameter of 2 mm, an optical transmission rate of ~ 65% to 75% in the wavelength range of 450 to 700 nm, a centre frequency of 15 MHz and a -6 dB bandwidth of 20 MHz. In the future, a forward-reviewing PAE probe will be developed based on this transparent sensor to guide minimally invasive procedures.
