Optoacoustic imaging and potential applications of raster-scan optoacoustic mesoscopy in dermatology
Clinics in Dermatology, 2022Optoacoustic imaging (OAI) is a hybrid imaging modality that integrates the benefits of optical contrast and ultrasound detection. Raster-scan optoacoustic mesoscopy (RSOM) is an emerging OAI method that provides information about several dermatological conditions' structural, functional, and molecular features.

Optoacoustic Imaging for Ophthalmology
Hybrid and Novel Imaging and New Optical Instrumentation for Biomedical Applications, 2001The feasibility of optoacoustic imaging was investigated for ophthalmologic application in the treatment of glaucoma. Difficulties in the treatment with laser cyclophotocoagulation are mainly due to uncertainties in the localization of the ciliary body.

Multimodal Optoacoustic Imaging
2018Optical imaging is one of the oldest and most frequently used imaging techniques. Even though the first optical imaging device, the light microscope, has been invented around 1590, the human eye has served the same purpose for centuries before that. With the advent of new technologies, such as efficient electronics, powerful lasers, sensitive detectors,

Imaging modalities play an increasing role in today's medical diagnostics. Among them, ultrasound (US) is one the most widespread techniques although it has relatively poor soft tissue contrast. Furthermore, US is poorly suited as a modality for molecular imaging (MI).Methods such as Doppler and contrast-enhanced US (CEUS) allow functional imaging of ...

Imaging with the optoacoustic effect
Optics & Laser Technology, 1980Abstract Optoacoustic imaging is a new technique with unusual features. It allows not only optical imaging, but also imaging of thermal structures on and in the sample. With optical radiation, images are produced from sample depths exceeding the optical penetration depth by several orders of magnitude. The resolution of, at present, about 7μm reveals

Iterative reconstruction algorithm for optoacoustic imaging
The Journal of the Acoustical Society of America, 2002Optoacoustic imaging is based on the generation of thermoelastic stress waves by heating an object in an optically heterogeneous medium with a short laser pulse. The stress waves contain information about the distribution of structures with preferential optical absorption.

Gigahertz optoacoustic imaging for cellular imaging
SPIE Proceedings, 2010Photoacoustic imaging exploits contrast mechanisms that depend on optical and thermomechanical properties of optical absorbers. The photoacoustic signal bandwidth is dictated by the absorber size and the laser pulse width. In this work we demonstrate that photoacoustic signals can be detected from micron and sub-micron particles.

Optical and Optoacoustic Imaging in the Diffusive Regime
2014Optical imaging is capable of providing valuable molecular contrast, cell tracking, genetic reporters, and a wide range of biomarkers that reveal the biological processes underlying a disease. For centuries, optical imaging has primarily been confined to superficial tissue layers, due to the high scattering of photons in tissue.

Optoacoustic ultrasound breast imaging is a fused anatomic and functional modality that shows morphologic features, as well as hemoglobin amount and relative oxygenation within and around breast masses. The purpose of this study is to investigate the positive predictive value (PPV) of optoacoustic ultrasound features in benign and malignant masses.In ...
