Side-Viewing Photoacoustic and Ultrasound Imaging Probe

The objective of this research is to develop a side viewing photoacoustic (PA) and ultrasound (US) imaging probe for biomedical applications. Utilizing borosilicate glass capillary tubes as both optical and acoustic waveguides allows for development of PA/US endoscopy probes with diameters much smaller than traditional PA/US endoscopy probes. This decrease in diameter of the PA/US endoscopy probe may facilitate minimally invasive imaging in the human body. In this work, the researchers custom 3D printed an acoustic/optical combiner to enable light and sound to travel efficiently through the hollow waveguide, while a custom-built rotation system enables 360-degree imaging.
