The optical imaging techniques available for clinical skin imaging are fundamentally limited in their depth scope to a few hundred microns and face difficulties in their functional and molecular imaging capabilities. Furthermore, histopathological analysis is still the only method of choice to accurately diagnose several skin diseases.

Optoacoustic imaging in five dimensions
SPIE Proceedings, 2015We report on an optoacoustic imaging system capable of acquiring volumetric multispectral optoacoustic data in real time. The system is based on simultaneous acquisition of optoacoustic signals from 256 different tomographic projections by means of a spherical matrix array.

Multimodal biomedical optoacoustic imaging
Conference on Lasers and Electro-Optics, 2016Optoacoustic imaging is a promising non-ionizing hybrid imaging modality combining high optical contrast and spectroscopic-based specificity of optical imaging with the high spatial resolution of ultrasound and speed of sound imaging.

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,

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.

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 ...

Real-time handheld multispectral optoacoustic imaging
Optics Letters, 2013Multispectral optoacoustic tomography (MSOT) of functional and molecular contrast has the potential to find broad deployment in clinical practice. We have developed the first handheld MSOT imaging device with fast wavelength tuning achieving a frame rate of 50 Hz.

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.
