  1. 1. Evaluating image analysis techniques for ultrasound optical tomography in breast tissue

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Henrik von Friesendorff; [2023]
    Nyckelord :ultrasound optical tomography; Monte Carlo light simulation; image reconstruction; Technology and Engineering;

    Sammanfattning : Breast cancer is the most commonly diagnosed cancer in the world today and early detection is crucial to minimize the mortality. ”Ultrasound optical tomography” (UOT) is a method under development for deep tissue imaging. LÄS MER

  3. 2. Ovary spheroid formation and quality assessment using two different protocols

    Master-uppsats, KTH/Proteinvetenskap

    Författare :Nikki Wallius Hiltunen; [2023]
    Nyckelord :ovary; fertility; spheroid; Biosilk™; three-layer gradient system; äggstock; fertilitet; sfäroid; Biosilk™; trelagers gradientsystem;

    Sammanfattning : Redan innan födseln fastställs kvinnors fertilitet, som karakteriseras av ett begränsat antal äggblåsor, så kallade folliklar. Beståndet av folliklar minskar naturligt med åldern, samtidigt som kvinnors fertilitet beror på deras steroid- och äggproduktion. LÄS MER

  4. 3. " Optimization of Margins and Plan Robustness for Proton Therapy of Hodgkin’s Lymphoma"

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Filip Hörberger; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose/Background: Utilizing proton therapy (PT) for treatment of Hodgkin’s lymphoma (HL) has demonstrated favorable features, particularly a reduced dose to organs at risk (OAR) in comparison with photon radiotherapy. However, there is a coherent complexity with PT including its uncertainties, such as range-uncertainties and set-up variations as protons are highly sensitive to tissue density variations within the beam-path.

  5. 4. 3D printer in dosimetry and mammography – designing and testing an OSL dosemeter holder and a low contrast-detail phantom

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Måns Boll; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications.

  7. 5. Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Jules Reniaud; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Magnetomotive Ultrasound, MMUS, is an imaging modality used to reveal a magnetic contrast agent using an external time-varying inhomogeneous magnetic field. By this, the particles are set in motion, and the motion is detected with ultrasound. LÄS MER
