In this paper, we demonstrate 3-D photoacoustic imaging (PAI) of light absorbing objects embedded as deep as 5 cm inside strong optically scattering phantoms using a miniaturized (4 mm × 4 mm × 500 µm), 2-D capacitive micromachined ultrasonic tran

Photoacoustic tomography is a rapidly growing imaging modality that can provide images of high spatial resolution and high contrast at depths up to 5 cm. We report here the design, synthesis, and evaluation of an activatable probe that shows great pr

Photoacoustic imaging of living subjects offers higher spatial resolution and allows deeper tissues to be imaged compared with most optical imaging techniques1,2,3,4,5,6,7. As many diseases do not exhibit a natural photoacoustic contrast, especially

As the use of ultrasonic transducers has increased so has the need to measure and characterize their pressure fields. Currently available hydrophones are limited by long scan times, and multiple source pulses to measure large area fields. Using a 2D

Photoacoustic molecular imaging is an emerging technology offering non-invasive high resolution imaging of the molecular expressions of a disease using a photoacoustic imaging agent. Here we demonstrate for the first time the utility of single walled

In this paper, we investigate using a large aperture (64 times 64 element array) to perform photoacoustic and acoustic imaging by mechanically scanning a smaller array (16 times 16 elements) of capacitive micromachined ultrasonic transducers (CMUTs).
