Photoacoustic imaging—a hybrid biomedical imaging modality finding its way to clinical
practices. Although the photoacoustic phenomenon was known more than a century back …

Significance Cutaneous melanoma (CM) has a high morbidity and mortality rate, but it can
be cured if the primary lesion is detected and treated at an early stage. Imaging techniques …

Photoacoustic imaging (PAI) is a newly emerging imaging modality for preclinical and
clinical applications. The conventional PAI systems use Q-switched Nd: YAG/OPO (Optical …

Accurate volumetric photoacoustic image reconstruction requires ultrasonic detection with
sufficient sensitivity to pressure transients over a broad spectral bandwidth. By using the …

Photoacoustic imaging (PAI) is a noninvasive biomedical imaging technology capable of
multiscale imaging of biological samples from organs down to cells. Multiscale PAI requires …

Owing to their extremely wide bandwidths, pure optical ultrasonic detection methods are
gaining increasing interest. In this Letter, we proposed a simple ultrasonic detector that is …

Enabling simultaneous high-resolution imaging of the total concentration of hemoglobin (C
Hb), oxygen saturation of hemoglobin (sO 2), and cerebral blood flow (CBF), multiparametric …

For biomedical photoacoustic applications, an ongoing challenge in simultaneous
volumetric imaging and spectroscopic analysis arises from ultrasonic detectors lacking high …

Optical ultrasonic probes, exemplified by Fabry–Perot cavities on optical fibers, have small
