Photoacoustic imaging (PAI) takes advantage of both optical and ultrasound imaging
properties to visualize optical absorption with high resolution and contrast. Photoacoustic …

Objective: Photoacoustic (PA) imaging emerges as a unique tool to study biological samples
based on optical absorption contrast. In PA imaging, piezoelectric transducers are …

Photoacoustic tomography (PAT), or optoacoustic tomography, has achieved remarkable
progress in the past decade, benefiting from the joint developments in optics, acoustics …

Increasing the imaging speed is a central aim in photoacoustic tomography. This issue is
especially important in the case of sequential scanning approaches as applied for most …

In photoacoustic imaging the ultrasonic signals are usually detected by contacting
transducers. For some applications contact with the tissue should be avoided. As …

Photoacoustic (PA) imaging may be advantageous as a safe, non-invasive imaging modality
to image the carotid artery. However, calcification that accompanies atherosclerotic plaque …

Cutting-edge biomedical ultrasound imaging demands advanced ultrasound sensing
capabilities such as broad bandwidth, high sensitivity, and parallel sensing. A variety of …

We present multimodal noncontact photoacoustic (PA) and optical coherence tomography
(OCT) imaging. PA signals are acquired remotely on the surface of a specimen with a Mach …

We report on a noncontact photoacoustic imaging system utilizing an all-fiber-optic
heterodyne interferometer as an acoustic wave detector. The acoustic wave generated by a …

Development of both fundamental research and clinical applications of photoacoustic
imaging call for ultrasound detectors of high sensitivity, flat frequency response, and …
