Fast Volumetric Imaging of Fluorescent Tissue Structures and Activities
Researchers at the University of Arizona have developed a novel microscope imaging technique that generates high-resolution large-volume 3D images of tissue at subcellular resolution, and captures transient activities within the volume at 100 volume frames per second (vps). The invention breaks away from the traditional plane-scanning approach and implements...

Method of Measuring Distorted Illumination Patterns and Correcting Image Artifacts in Structured Illumination Imaging
This technology is an improvement to the well-established microscopy technique structured illumination microscopy (SIM), which uses a periodic structured pattern of light to image a sample. In SIM, it is common for artifacts to arise during imaging, because the pattern is often distorted due to aberration and index mismatches in samples. These artifacts...
