Fast Tissue Clearing and Volume Imaging Techniques for Anatomy

Microscopy Research and Technique, EarlyView.
Tissue clearing and volume imaging techniques have revolutionized our ability to visualize large biological samples, but they face obstacles related to speed, tissue preservation, complexity, and the need for fluorescence labels that make them difficult to implement in anatomy and preclinical research.

Correction of the effects of acoustic heterogeneity on thermoacoustic tomography using transmission ultrasound tomography [PDF]

, 2006
The effects of acoustic heterogeneities on thermoacoustic tomography (TAT) are examined and corrected. One assumption made in the existing reconstruction algorithms for thermoacoustic tomography is that biological tissue is acoustically homogeneous.

Illuminating Satellite Cells: Light Sheet Fluorescence Microscopy for 3D Imaging of Murine Skeletal Muscles Damaged by Ex Vivo Forced Eccentric Contraction

Microscopy Research and Technique, EarlyView.
This study presents the light sheet fluorescence microscopy (LSFM) as a tool for 3D‐imaging of whole skeletal muscle to reveal satellite cells (SCs), the muscle stem cells that activate following damage to repair injured tissue. After tissue clearing and whole‐mount staining process aimed to enable optical access and specific cell labeling (1), murine ...

Continuous‐Wave Laser‐Driven Cascaded Harmonic Generation in a Periodically Poled Lithium Niobate Racetrack Resonator

Laser &Photonics Reviews, EarlyView.
This work demonstrates efficient continuous‐wave‐driven cascaded harmonic generation up to the ultraviolet in a periodically poled thin‐film lithium niobate racetrack resonator. Using a single poling period and telecom‐band laser input, the device achieves second harmonic generation with 2,200% W−1${\rm W}^{-1}$ efficiency and supports third and fourth

Tightly‐Confined and Long Z‐Cut Lithium Niobate Waveguide with Ultralow‐Loss

Laser &Photonics Reviews, EarlyView.
A z‐cut lithium niobate waveguide is demonstrated with ultra‐low loss of 5.8 dB/m in a decimeter‐long LN spiral waveguide. This study is focused on Z‐cut LN waveguides with TE mode to avoid the material birefringence. Utilizing the third order nonlinearity, it is demonstrated that the first all‐normal‐dispersion coherent supercontinuum frequency comb ...
