  1. 1. Computerized Cell and Tissue Analysis

    Författare :Azadeh Fakhrzadeh; Gunilla Borgefors; Cris Luengo Hendriks; Lena Holm; Nasir Rajpoot; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Image processing; Cell; Tissue; Segmentation; Classification; Histology; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : The latest advances in digital cameras combined with powerful computer software enable us to store high-quality microscopy images of specimen. Studying hundreds of images manually is very time consuming and has the problem of human subjectivity and inconsistency. LÄS MER

  3. 2. Methods, Instrumentation and Mechanisms for Optical Characterization of Tissue and Treatment of Malignant Tumours

    Författare :Sara Pålsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; temperature; perfusion; PDT; photodynamic therapy; mechanisms; tissue characterization; instrumentation; optical biopsy; fluorescence spectroscopy; spectroscopy techniques; Raman spectroscopy; interstitial photodynamic therapy; photodynamic threshold dose; Atomic and molecular physics; Atom- och molekylärfysik;

    Sammanfattning : In this thesis, different optical methods utilising visible light for characterization of tissue have been developed and evaluated. The feasibility of many of these methods has been demonstrated in the laboratory or in animal experiments. LÄS MER
