  1. 1. Karakterisering av en mikrosensorsnål för mätning av syrehalt och konduktivitet

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Gustav Raittila; [2024]
    Nyckelord :Akupunkturnål; konduktivitetsmätning; medicintekniskprodukt; mikrosensor; syremätning;

    Sammanfattning : This report focuses on the characterization of an acupuncture needle microsensor, designed tomeasure the conductivity and oxygen saturation of tissues in the body, in particular musculartissues. The device is intended to help the practitioner localize and treat sources of chronicneuromuscular pain in patients. LÄS MER

  3. 2. A Machine Learning Approach to Skin Cancer Delineation on Photoacoustic Imaging

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Alice Fracchia; [2023]
    Nyckelord :Skin cancer; carcinoma; photoacoustic imaging; ultrasound imaging; machine learning; dimensionality reduction; sandpiles algorithm; active contour; multilayer perception MLP ; convolutional neural networks CNN ; autoencoder; Physics and Astronomy;

    Sammanfattning : Skin cancer is a growing public health concern due to its prevalence among the population. Current clinical procedures require high invasiveness and multiple surgeries, which are responsible for patient discomfort and high medical expenses. LÄS MER

  4. 3. Designing a bioreactor to test mechanical properties of decellularized heart valves

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Viktor Börjesson; Oskar Gögelein; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Aortic valvular disease is a severe ailment that causes great suffering and many deaths worldwide. The exponentially increasing prevalence of the disease has accelerated the demand of a new functioning valve prosthesis. A new approach is to decellularize homograft heart valves, which has demonstrated promising results in clinical trials. LÄS MER

  5. 4. Characterization of monkey fat tissues : To assist their viability for fat intra-body communication as an early step of non-human primate testing (NHP)

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Qsai Alyounes; Alkari Razan; [2022]
    Nyckelord :Fat-IBC; Monkey tissues; Phantoms; Network analyzer; Dielectric proporties;

    Sammanfattning : Fat intra-body communication is a newly proven concept that is built on using human fat tissues as a communication channel for electromagnetic waves inside the body. This allows for two implanted external devices to connect through an intra-body closed-loop communication channel. LÄS MER

  7. 5. The Investigation of Crack Propagation in Cortical Bone using a Phase Field Fracture Approach

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Olivia Karlsson; [2022]
    Nyckelord :Cortical Bone; Cortical bone microstructure; Phase field; Phase field fracture approach; Crack propagation; Technology and Engineering;

    Sammanfattning : Human cortical bone tissue is a complex and strong composite material, with the ability to resist damage via slowing, stopping or redirecting propagating cracks. However, the ability is impaired with age. At the microscale, changes are seen both in terms of increased porosity and as changes in local material parameters. LÄS MER
