  1. 1. FTIR spectroscopy of glucose

    Kandidat-uppsats, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Louise Nybacka; [2016]
    Nyckelord :FTIR; Spectroscopy; Glucose;

    Sammanfattning : Approximately 450 000 people have diabetes in Sweden today, and the number of diabetics only rises. Monitoring blood sugar several times a day is a fundamental part of managing the disease, and reducing the risks of complications. Today’s glucose monitoring devices are invasive and require small needle sticks for a measurement. LÄS MER

  3. 2. Diffuse reflectance spectroscopy as a tool to evaluate liver tissue

    Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Atomfysik

    Författare :Therese Alburg; David Kraus; [2014]
    Nyckelord :diffuse reflectance spectroscopy; drs; biophotonics; medical optics; diffusion; tissue evaluation; Technology and Engineering;

    Sammanfattning : The shape of a diffuse reflectance spectra can provide knowledge about tissue composition. By analysing this spectra one can, with the right evaluation methods, find out information about the tissue. LÄS MER

  4. 3. Photon time-of-flight and continuous-wave near-infrared-spectroscopy of human skeletal muscle tissue; a comparative study

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Matematisk fysik

    Författare :Alfi Shaharin; [2013]
    Nyckelord :Photon time-of-flight spectrometer; pTOFS; Tissue Saturation; StO2; and CW-NIRS; Physics and Astronomy;

    Sammanfattning : The focus of this thesis is to perform a comparative study between two noninvasive optical techniques: Photon Time-of-flight Spectroscopy (pTOFS) and a Continuous-wave NIRS system for measuring muscle tissue oxygen saturation. INVOS 5100C (Manufactured in 2011, Serial Number 11-10269, Produced by Somanetics Troy, MI 48084 USA) is such a CW-NIRS system that provides tissue oxygenation using continuous wave Near Infrared Spectroscopy technique and widely used in the hospitals.

  5. 4. Blood interference in fluorescence spectrum : Experiment, analysis and comparison with intraoperative measurements on brain tumor

    Kandidat-uppsats, Linköpings universitet/Biomedicinsk instrumentteknik; Linköpings universitet/Tekniska högskolan

    Författare :Shannely Lowndes; [2010]
    Nyckelord :autofluorescence; blood absorption spectra; diffuse reflection spectroscopy; optical touch pointer; intraoperative optical measurements;

    Sammanfattning : The optical touch pointer (OTP), a fluorescence spectroscopy based system, assists brain surgeons during guided brain tumor resection in patients with glioblastoma multiforme (GBM). After recording and analyzing the autofluorescence spectrum of the tissue, it is possible to distinguish malignant from healthy brain tissue. LÄS MER
