  1. 1. Developing Automated Cell Segmentation Models Intended for MERFISH Analysis of the Cardiac Tissue by Deploying Supervised Machine Learning Algorithms

    Master-uppsats, KTH/Kemi

    Författare :Julia Rune; [2023]
    Nyckelord :Cell Segmentation; Cellpose; Supervised Machine Learning; MERFISH; Heart Failure; Cellsegmentering; Cellpose; Övervakad Maskininlärning; MERFISH; Hjärtsvikt;

    Sammanfattning : Följande studie behandlar utvecklandet av automatiserade cellsegmenteringsmodeller med avsikt att identifiera gränser mellan celler i hjärtvävnad. Syftet är att möjliggöra analys av data genererad från multiplexed error-robust in situ hybridization (MERFISH). 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. X-Ray Tomography on Intestine Samples

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Julia Rogalinski; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : 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. LÄS MER

  5. 4. Design and evaluation of a novel Transillumination SFDI system for quantitative assessment of tissuesections for rapid, label-free cancer margin detection

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Merel Younan; [2023]
    Nyckelord :SFDI; transillumination SFDI system; tissue-conserving surgeries; thin layers; tissue analysis; skin cancer;

    Sammanfattning : This study investigates the potential of Spatial Frequency Domain Imaging (SFDI) as a non-invasive imaging technique for tissue analysis in the context of Mohs surgery, a standard procedure for skin cancer removal with margin control. The current practice of performing multiple histopathologic sections during the procedure is time-consuming and labor-intensive. LÄS MER

  7. 5. Impact of the autoencoder-based FINTA tractogram filtering method on brain networks in subjects with Mild Cognitive Impairment

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Teodor Pstrusiński; [2023]
    Nyckelord :Tractography; Autoencoder; diffusion MRI; Filtering; Graph; Connectome; Traktografi; Autoencoder; diffusions MRT; Filtrering; Graf; Konnektom;

    Sammanfattning : Diffusion Magnetic Resonance Imaging (dMRI) is a method for measuring molecular diffusion in biological tissue microstructure. This information can be used to predict the location and orientation of white matter fibers in the brain, a process known as tractography. LÄS MER
