  1. 1. Identification of Fibers in Micro-CT Images of Paperboard Using Deep Learning

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : David Rydgård; [2023]
    Keywords : Fiber networks; Paperboard mechanics; Deep learning; Tomography; Image analysis; Technology and Engineering;

    Abstract : This master thesis project explores the possibility of using deep learning to segment individual fibers in three-dimensional tomography images of paperboard fiber networks. We test a method which has previously been used to segment fibers in images of glass fiber reinforced polymers. READ MORE

  3. 2. Deep Learning Based Detection, Quantification, and Subdivision of White Matter Hyperintensities in Brain MRI

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Inna Fryckstedt; [2023]
    Keywords : white matter hyperintensities; white matter lesions; deep learning; machine learning; DL; ML; MRI; iNPH;

    Abstract : White matter hyperintensities (WMH) are commonly found as bright regions in brain MRI images in older individuals. They are associated with various neurological and vascular diseases, such as stroke, dementia, and cardiovascular disorders. READ MORE

  4. 3. Method for the classification of brain cancer treatment's responsiveness via physical parameters of DCE-MRI data

    University essay from Stockholms universitet/Fysikum

    Author : Georgia Kanli; [2015]
    Keywords : DCE-MRI; pharmacokinetic modeling; perfusion imaging; brain tumor; patient classification;

    Abstract : Tumors have several important hallmarks; anomalous and heterogeneous behaviors of their vascular structures, and high angiogenesis and neovascularization. Tumor tissue presents high blood flow (F) and extraction ratio (E) of contrast molecules. READ MORE

  5. 4. Three material decomposition in dual energy CT for brachytherapy using the iterative image reconstruction algorithm DIRA : Performance of the method for an anthropomorphic phantom

    University essay from Institutionen för medicinsk teknik; Tekniska högskolan

    Author : Robin Westin; [2013]
    Keywords : DECT; Iterative reconstruction; Tissue decomposition; Numerical stability; Uncertainty propagation;

    Abstract : Brachytherapy is radiation therapy performed by placing a radiation source near or inside a tumor. Difference between the current water-based brachytherapy dose formalism (TG-43) and new model based dose calculation algorithms (MBSCAs) can differ by more than a factor of 10 in the calculated doses.

  6. 5. Visualization of Regional Liver Function with Hepatobiliary Contrast Agent Gd-EOB-DTPA

    University essay from Institutionen för medicin och hälsa

    Author : Johanna Samuelsson; [2011]
    Keywords : k-means; kNN; IFT; model; pharmacokinetics;

    Abstract : Liver biopsy is a very common, but invasive procedure for diagnosing liver disease. However, such a biopsy may result in severe complications and in some cases even death. READ MORE
