Label-free three-dimensional imaging of Caenorhabditis elegans with visible optical coherence microscopy

Johan Auwerx, Theo Lasser, Laurent Mouchiroud, Paul James Marchand, Arno Pino Bouwens, Vincenzo Sorrentino, Daniel Pawel Szlag, Séverine Coquoz

Fast, label-free, high-resolution, three-dimensional imaging platforms are crucial for high-throughput in vivo time-lapse studies of the anatomy of Caenorhabditis elegans, one of the most commonly used model organisms in biomedical research. Despite the ne ...

Extended-focus optical coherence microscopy for high-resolution imaging of the murine brain

Theo Lasser, Daniel Pawel Szlag

We propose a new method and optical instrumentation for mouse brain imaging based on extended-focus optical coherence microscopy. This in vivo imaging technique allows the evaluation of the cytoarchitecture at cellular level and the circulation system dyna ...

MR Image Reconstruction from Generalized Projections

Daniel Gallichan

Purpose: Currently, the time required for image reconstruction is prohibitively long if data are acquired using multidimensional imaging trajectories that make use of multichannel systems equipped with nonlinear gradients. Methods are presented that reduce ...

Eigensensing And Deconvolution For The Reconstruction Of Heat Absorption Profiles From Photoacoustic Tomography Data

Dimitri Nestor Alice Van De Ville, Thierry Blu, Zafer Dogan

Photoacoustic tomography (PAT) is a relatively recent imaging modality that is promising for breast cancer detection and breast screening. It combines the high intrinsic contrast of optical radiation with acoustic imaging at submillimeter spatial resolutio ...

Characterization of the cytotoxicity and imaging properties of secondharmonic nanoparticles

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh

We develop second-harmonic nanoparticles as the contrast agents for cell imaging. Second-harmonic nanoparticles show promise as cell imaging probes due to their non-bleaching, non-blinking, and coherent signal. Nanoparticles of noncentrosymmetric crystal s ...

Barium titanate nanoparticles used as second harmonic radiation imaging probes for cell imaging

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh

Luminescent markers play a key role in imaging techniques for life science since they provide a contrast mechanism between signal and background. We describe a new type of marker using second harmonic generation (SHG) from noncentrosymmetric BaTiO3 nanocry ...

Extended focus optical coherence microscopy and fluorescence lifetime imaging

Theo Lasser, Rainer Leitgeb, Martin Villiger, Adrian Bachmann, Cédric Blatter

Fourier domain Optical coherence microscopy (FDOCM) offers excellent sensitivity and high axial resolution to image the structure of biological tissue. The depth information is extracted in parallel and allows very high volume acquisition rates. The presen ...

Luminescent lanthanides bioprobes emitting in the visible and/or near-infrared ranges

Steve Comby

This Ph.D. work deals with the development of lanthanide-based bioprobes for biomedical analyses and imaging. For this purpose, two different approaches have been followed, one focusing on visible-emitting complexes, while the second addresses the sensitiz ...

Tomographic reconstruction of three-dimensional objects from hard X-ray differential phase contrast projection images

Christian David

We report on a method for tomographic phase contrast imaging of centimeter sized objects. As opposed to existing techniques, our approach can be used with low-brilliance, lab based X-ray sources and thus is of interest to a wide range of applications in me ...
