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

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Alice Fracchia; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Viktor Börjesson; Oskar Gögelein; [2023]
    Keywords : Technology and Engineering;

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Institutionen för materialvetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

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

    Abstract : 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. READ MORE

  6. 5. The impact of ion drift in a Transcutaneous Electrical Stimulation model

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Oscar Tuvesson; Erik Blåe; [2022]
    Keywords : TES; neuron activation; ion drift; conductivity; COMSOL; FEM; Technology and Engineering;

    Abstract : A major area of research in neuroscience is the effect of stimulating nerves into activation from extrinsic stimuli. This is commonly done with electric currents and external skin-contact electrodes. READ MORE
