  1. 1. Phase-Contrast and High-Resolution Optics for X-Ray Microscopy

    University dissertation from Stockholm : KTH

    Author : Olof von Hofsten; KTH.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microscopy; X-ray optics; X-ray microscopy; Soft X-ray physics; NATURAL SCIENCES Physics Other physics Optics; NATURVETENSKAP Fysik Övrig fysik Optik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : X-ray microscopy is a well-established technique for nanoscale imaging. Zone plates are used as microscope objectives and provide high resolution, approaching 10 nm, currently limited by fabrication issues. This Thesis presents zone plate optics that achieve either high resolution or phase contrast in x-ray microscopy. READ MORE

    Abstract : Soft x-ray microscopy in the water-window (λ = 2.28 nm – 4.36 nm) is based on zone-plate optics and allows high-resolution imaging of, e.g. READ MORE

  3. 3. Deep Neural Networks and Image Analysis for Quantitative Microscopy

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sajith Kecheril Sadanandan; Uppsala universitet.; Uppsala universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deep neural networks; convolutional neural networks; image analysis; quantitative microscopy; bright-field microscopy; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Understanding biology paves the way for discovering drugs targeting deadly diseases like cancer, and microscopy imaging is one of the most informative ways to study biology. However, analysis of large numbers of samples is often required to draw statistically verifiable conclusions. READ MORE

  4. 4. Towards High-Throughput Phenotypic and Systemic Profiling of in vitro Growing Cell Populations using Label-Free Microscopy and Spectroscopy Applications in Cancer Pharmacology

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Obaid Aftab; Uppsala universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; label free vesicle detector; high-throughput; phase contrast microscopy; Library of Pharmacologically Active Compounds; High Content Screening; fluorometric microculture cytotoxicity assay; nuclear magnetic resonance; mass spectrometry;

    Abstract : Modern techniques like automated microscopy and spectroscopy now make it possible to study quantitatively, across multiple phenotypic and molecular parameters, how cell populations are affected by different treatments and/or environmental disturbances. As the technology development at the instrument level often is ahead of the data analytical tools and the scientific questions, there is a large and growing need for computational algorithms enabling desired data analysis.
