Hyperspectral analysis using the correlation between image and reference
(Journal article; Peer reviewed, 2013)We present the use of correlation analysis on spectral data in order to quantify the amount of a given spectrum present with respect to a reference spectrum. The method is shown to be useful in analyzing hyperspectral ... -
Mueller matrix three-dimensional directional imaging of collagen fibers
(Journal article; Peer reviewed, 2014)A method for measuring three-dimensional (3-D) direction images of collagen fibers in biological tissue is presented. Images of the 3-D directions are derived from the measured transmission Mueller matrix images (MMIs), ... -
Quantitative 3-D colocalization analysis as a tool to study the intracellular trafficking and dissociation of pDNA-chitosan polyplexes
(Journal article; Peer reviewed, 2012)Multichannel microscopy is frequently used to study intermolecular interactions and spatial relationships between biomolecules and organelles or vesicles in cells. Based on multichannel images, quantitative colocalization ... -
Quantitative characterization of articular cartilage using Mueller matrix imaging and multiphoton microscopy
(Journal article; Peer reviewed, 2011)The collagen meshwork in articular cartilage of chicken knee is characterized using Mueller matrix imaging and multiphoton microscopy. Direction and degree of dispersion of the collagen fibers in the superficial layer are ... -
Recovering fluorophore concentration profiles from confocal images near lateral refractive index step changes
(Peer reviewed; Journal article, 2016)Optical aberrations due to refractive index mismatches occur in various types of microscopy due to refractive differences between the sample and the immersion fluid or within the sample. We study the effects of lateral ... -
Red versus blue light illumination in hexyl 5-aminolevulinate photodynamic therapy: the influence of light color and irradiance on the treatment outcome in vitro
(Journal article; Peer reviewed, 2014)Abstract. Hexyl 5-aminolevulinate (HAL) is a lipophilic derivative of 5-aminolevulinate, a key intermediate in biosynthesis of the photosensitizer protoporphyrin IX (PpIX). The photodynamic efficacy and cell death mode ... -
Spectral correlation analysis of Amyloid beta plaque inhomogeneity from double staining experiments
(Journal article; Peer reviewed, 2013)A spectral correlation algorithm for the analysis of hyperspectral fluorescence images is proposed by Ellingsen et al. [J. Biomed. Opt. 18, 020501 (2013)]. Here, it is applied to the analysis of double-stained Aβ amyloid ...
