  3. 2. Direct optimization of dose-volume histogram metrics in intensity modulated radiation therapy treatment planning

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Tianfang Zhang; [2018]
    Nyckelord :Optimization; intensity-modulated radiation therapy; DVH functions; dose-at-volume; volume-at-dose; value-at-risk; smooth approximation; kernel density estimation; fluence map optimization; Optimering; intensitetsmodulerad strålterapi; DVH-funktioner; dose-at-volume; volumeat- dose; value-at-risk; slätapproximation; ickeparametrisk skattning; fluensoptimering;

    Sammanfattning : In optimization of intensity-modulated radiation therapy treatment plans, dose-volumehistogram (DVH) functions are often used as objective functions to minimize the violationof dose-volume criteria. Neither DVH functions nor dose-volume criteria, however,are ideal for gradient-based optimization as the former are not continuously differentiableand the latter are discontinuous functions of dose, apart from both beingnonconvex.

  4. 3. Development of narrow-bandwidth filters for the suppression of scattered light for optical and ultrasound analysis of tissue

    Magister-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Philip Dalsbecker; [2015]
    Nyckelord :biophotonics; Maxwell-Bloch equations; tissue; ultrasound; Ultrasound-modulated optical tomography; UOT; Physics and Astronomy;

    Sammanfattning : Ultrasound-modulated optical tomography (UOT) is a proposed diagnostic technique with potential as a means of discovering cancerous tumours. The technique combines ultrasound and laser radiation to probe tissue in a non-invasive, harmless way. LÄS MER

  5. 4. The Ising Model on a Heavy Gravity Portfolio Applied to Default Contagion

    Magister-uppsats, Tillämpad matematik och fysik (MPE-lab)

    Författare :Yang Zhao; Min Zhang; [2011]
    Nyckelord :Financial Mathematics; Ising model; portfolio; default contagion;

    Sammanfattning : In this paper we introduce a model of default contagion in the financail market. The structure of the companies are represented by a Heavy Gravity Portfolio, where we assume there are N sectors in the market and in each sector i, there is one big trader and ni supply companies.
