  1. 6. 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

  3. 7. Novel combined fluorescence/reflectance spectroscopy system for guiding brain tumor resections

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

    Författare :Zhiyuan Xie; [2013]
    Nyckelord :fiber optic sensors; fluorescence spectroscopy; reflectance; tissues; light-emitting diodes; ambient light rejection; modulation thniques; delusion experiment; medical optics instrumentation; Matlab; Labview.; Physics and Astronomy;

    Sammanfattning : This thesis describes a system developed for assisting Glioblastoma multiforme (GBM) brain tumor surgery. The thesis starts with providing some facts of GBM tumor, and introduces some traditional diagnostic methods and their short comes. In the later chapters, the system development details and some tests for the system performances are described.. LÄS MER

  4. 8. Optimization of X-ray Source for Digital Mammography -  X-ray Optics Approach

    Master-uppsats, Institutionen för medicinsk teknik; Tekniska högskolan

    Författare :Mineh Nazary; [2012]
    Nyckelord :;

    Sammanfattning : The work presents a new design of X-ray source for digital mammography imaging with the help of crystal sources and X-ray optics technology. The aim of the project was to introduce a new source for medical x ray imaging and evaluate its ability of performance. The source is build of an array of multiple micro-emitters instead of a single source. LÄS MER

  5. 9. Sjukdom som Poesi

    Master-uppsats, Lunds universitet/Läkarutbildningen

    Författare :Birgitta Sundström; [2012]
    Nyckelord :Medical Humanities; Medicine and literature; Medicine and poetry; Medicine and Health Sciences;

    Sammanfattning : Föreliggande examensarbete i Medical Humanities har utförts för att pröva lyrikens möjligheter i medicinsk utbildning och fortbildning. Skönlitteratur används i utbildningen av läkare i Sverige men lyrik är en hittills outnyttjad resurs i detta sammanhang. LÄS MER

  7. 10. Electrical and Optical Characterization of InP Nanowire Ensemble Photodetectors

    Magister-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Tuan Nghia Ngo; Irina Zubritskaya; [2012]
    Nyckelord :InP; Nanowire; Wurtzite; Zincblende; Photodetector; Semiconductor;

    Sammanfattning : Photodetectors are semiconductor devices that can convert optical signals into electrical signals. There is a wide range of photodetector applications such as fiber optics communication, infrared heat camera sensors, as well as in equipment used for medical and military purposes. LÄS MER
