Photoacoustic imaging (PAI) is an emerging biomedical imaging modality that is based on
optical absorption contrast, capable of revealing distinct spectroscopic signatures of tissue at …

Photoacoustic imaging is a rapidly maturing imaging modality in biological research and
medicine. This modality uses the photoacoustic effect (“light in, sound out”) to combine the …

In photoacoustic imaging, delay-and-sum (DAS) beamformer is a common beamforming
algorithm having a simple implementation. However, it results in a poor resolution and high …

Imaging has become an indispensable tool in the research and clinical management of
cardiovascular disease (CVD). An array of imaging technologies is considered for CVD …

Endoscopy has been widely used in biomedical imaging and integrated with various optical
and acoustic imaging modalities. Photoacoustic imaging (PAI), one of the fastest growing …

Photoacoustic tomography (PAT) combines rich optical absorption contrast with the high
spatial resolution of ultrasound at depths in tissue. The high scalability of PAT has enabled …

Despite exciting advances in structural intravascular imaging [intravascular ultrasound
(IVUS) and optical coherence tomography (OCT)] that have enabled partial assessment of …

We present a tri-modality imaging system and fully integrated tri-modality probe for
intravascular imaging. The tri-modality imaging system is able to simultaneously acquire …

Endoscopic dual-modality photoacoustic (PA) and ultrasound (US) imaging has the
capability of providing morphology and molecular information simultaneously. An ultrasonic …

Plane strain tensor estimation using non-invasive vascular ultrasound elastography (NIVE)
can be difficult to achieve using conventional focus beamforming due to limited lateral …
