  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. Examination of suitable material for phantoms used in photoacoustics

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Malin Larsson; Klara Wahldén; [2022]
    Keywords : Photoacoustics; PIA; Center frequency spectrum; Technology and Engineering;

    Abstract : A fundamental part of modern medicine is the ability to study and analyze images, especially for diagnostic purposes. A relatively new imaging system is photoacoustics, where laser- and ultrasound technology are combined to create images in a non-invasive way. READ MORE

  4. 3. Characterization of Iron Oxide Nanoparticle-Based Contrast Agent in Photoacoustic Imaging and Magnetic Resonance Imaging

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Jimmy Zheng; [2021]
    Keywords : Photoacoustic imaging; magnetic resonance imaging; iron oxide nanoparticle; multimodal contrast agent;

    Abstract : Pancreatic ductal adenocarcinoma (PDAC) is one of the most difficult type of cancer to treat, due to late diagnosis which is a result of vague symptoms and lack of biomarkers, as well as refractory behavior toward current treatment protocols. Imaging of the disease progression therefore plays a crucial role in identifying potentially curable PDAC patients at an early stage. READ MORE

  5. 4. Development and characterization of tissue-mimicking phantom materials for photoacoustic imaging

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Chen Xu; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Tissue-mimicking phantoms are of great interest in the development of bio-medical applications. Instead of applying to biological tissues directly, phantoms enable stable and easy accessibility to validate spectroscopy systems and measuring processes. This thesis project is centered on the development and characterization of phantoms. READ MORE
