Intravascular photoacoustic imaging of human coronary atherosclerosis.
We demonstrate intravascular photoacoustic imaging of human coronary atherosclerotic plaque. The data was obtained from two fresh human coronary arteries ex vivo, showing different stages of disease.Expand

Intravascular photoacoustic imaging: a new tool for vulnerable plaque identification.
The vulnerable atherosclerotic plaque is believed to be at the root of the majority of acute coronary events. Even though the exact origins of plaque vulnerability remain elusive, the thin-capExpand

Intravascular photoacoustic imaging of human coronary atherosclerosis
We demonstrate intravascular photoacoustic imaging of human coronary atherosclerotic plaque. We specifically imaged lipid content, a key factor in vulnerable plaques that may lead to myocardialExpand

Specific imaging of atherosclerotic plaque lipids with two-wavelength intravascular photoacoustics.
The lipid content in plaques is an important marker for identifying atherosclerotic lesions and disease states. Intravascular photoacoustic (IVPA) imaging can be used to visualize lipids in theExpand

Impact of device geometry on the imaging characteristics of an intravascular photoacoustic catheter.
A basic requirement for intravascular photoacoustic (IVPA) imaging catheters is that the delivery of light lies within the ultrasonic field of view. Size and manufacturing constraints favor probeExpand

Photoacoustic imaging of human coronary atherosclerosis in two spectral bands☆
Spectroscopic intravascular photoacoustic imaging (sIVPA) has shown promise to detect and distinguish lipids in atherosclerotic plaques. sIVPA generally utilizes one of the two high absorption bandsExpand

Spectroscopic intravascular photoacoustic imaging of lipids in atherosclerosis
Abstract. The natural history of atherosclerosis is marked by changes in the lipid biochemistry in the diseased arterial wall. As lesions become more vulnerable, different cholesterol speciesExpand

Lipid detection in atherosclerotic human coronaries by spectroscopic intravascular photoacoustic imaging.
The presence of lipids in atherosclerotic coronary lesions is an important determinant of their potential to trigger acute coronary events. Spectroscopic intravascular photoacoustic imaging (sIVPA)Expand

Imaging microvasculature with contrast-enhanced ultraharmonic ultrasound.
Atherosclerotic plaque neovascularization was shown to be one of the strongest predictors of future cardiovascular events. Yet, the clinical tools for coronary wall microvasculature detection in vivoExpand

Intravascular ultrasound chirp imaging
We demonstrate the feasibility of intravascular ultrasound chirp imaging. Chirp excitations were emitted with a 34 MHz single crystal intravascular transducer and compared to conventional GaussianExpand
