TL;DR: A new cycloid scanner in a tethered capsule for ultrahigh speed, side-viewing optical coherence tomography (OCT) endomicroscopy in vivo is demonstrated and promises to enable precision 2D optical scanning for other imaging modalities, including fluorescence confocal and nonlinear microscopy.

TL;DR: An angular spectrum algorithm is presented for fast, near-field diffraction tomographic imaging with diffuse photon density waves in highly scattering media and a general relation in K space is derived that connects the spatial variations of the optical properties of heterogeneities to the spatial spectra of the measured scattered diffuse photondensity waves.

TL;DR: Overall this hydrophilic NIR fluorescent contrast agent exhibits excellent photophysical characteristics and low cytotoxicity, and holds a strong promise for a variety of applications including bioimaging and therapy.

TL;DR: A cross-referencing method is reported to quickly and accurately characterize the optical properties of nanoparticles including the extinction, scattering, absorption and backscattering cross sections by using an OCT system alone and provides a general guideline on choosing the optimal concentration and optical properties for the nanoparticle-based OCT contrast agents.

TL;DR: This work introduces two filtering methods for near-field diffuse light diffraction tomography based on the angular spectrum representation and combines these techniques with a new method to find the approximate depth of the image heterogeneities.
