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

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

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

    Abstract : 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. READ MORE

  3. 2. Improving the experimental setup for ultrasound-optical tomography imaging

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Ibtisam Dahir Ahmed; [2023]
    Keywords : Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

    Abstract : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. READ MORE

    Keywords : Physics and Astronomy;

    Abstract : Enteric neuropathy describes a disease of the bowel caused by anomalies in the enteric nervous system. Patients suffering from this disease have symptoms including nausea, vomiting, diarrhea and pain. As enteric neuropathy is not well understood yet, its diagnosis is a non-trivial task. READ MORE

  5. 4. Exploratory study on Additive Manufacturing in Urban mobility

    University essay from

    Author : Kaustubh Deshmukh; [2023]
    Keywords : ;

    Abstract : This thesis report presents a comprehensive study on the design and development of an Additively manufactured Unit cell for car door panels, aiming to enhance impact resistance and reduce noise transmission to the vehicle cabin. In order to accomplish these goals, the study focuses on combining two novel techniques namely quasi-zero stiffness (QZS) structures and phononic crystals (both scattering and locally resonating type).

  6. 5. Testing the detectability of supernova ejecta from Population III stars with future ELT/ANDES

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Aron Kordt; [2023]
    Keywords : ;

    Abstract : The first stars, known as Population III (Pop III) stars, formed when the Universe was about 100 Myr to 200 Myr old. In contrast to the present-day Universe, star formation took place in a basically metal-free environment. Despite several decades of research, Pop III stars have not yet been directly observed.
