  1. 16. Automatic Detection of Common Signal Quality Issues in MRI Data using Deep Neural Networks

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Erika Ax; Elin Djerf; [2023]
    Keywords : mr; magnetic resonance; machine learning; deep learning; anomaly detection; U-Net; autoencoder; 3D; classification; reconstruction; artefacts;

    Abstract : Magnetic resonance imaging (MRI) is a commonly used non-invasive imaging technique that provides high resolution images of soft tissue. One problem with MRI is that it is sensitive to signal quality issues. The issues can arise for various reasons, for example by metal located either inside or outside of the body. READ MORE

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

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

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

    Abstract : 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. READ MORE

  4. 18. Development of a tool for analysis and visualization of longitudinal magnetic resonance flowmeasurements : of subarachnoid hemorrhage patients in the neurointensivecare unit

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : ILDI ADOK; [2023]
    Keywords : 2D phase contrast MRI; subarachnoid hemorrhage; cerebral blood flow; visualization; neurointensive care;

    Abstract : Patients who are treated in an intensive care unit need continuous monitoring in orderfor clinicians to be prepared to intervene should a secondary event occur. For patientstreated at the neurointensive care unit (NICU) who have suffered a subarachnoid hemorrhage (SAH) this secondary event could be ischemia, resulting in a lack of blood flow. READ MORE

  5. 19. How to Estimate Local Performance using Machine learning Engineering (HELP ME) : from log files to support guidance

    University essay from Linköpings universitet/Artificiell intelligens och integrerade datorsystem

    Author : Hugo Ekinge; [2023]
    Keywords : Machine learning; GRU; 1D-CNN; Transformer; log analysis; parameter estimation; regression; performance monitoring; deep learning; troubleshooting; support; Maskininlärning; GRU; 1D-CNN; Transformer; logganalys; parameteruppskattning; regression; prestandaövervakning; djupinlärning; felsökning; support;

    Abstract : As modern systems are becoming increasingly complex, they are also becoming more and more cumbersome to diagnose and fix when things go wrong. One domain where it is very important for machinery and equipment to stay functional is in the world of medical IT, where technology is used to improve healthcare for people all over the world.

  6. 20. Lignin in Cosmetics: State of the Art : Discerning the value of lignin in the cosmetic industry

    University essay from Uppsala universitet/Industriell teknik; Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Author : Nellie Henriksson; Klas Nordell; [2023]
    Keywords : Lignin; Cosmetics; Personal care; Innovation; Cosmetic industry; Functional materials. Biotechnology; functional materials; green chemistry; Lignin; kosmetik; kosmetikaindustrin; Bioteknik; Nanomaterial; SPF; UV;

    Abstract : This study was carried out at the Department of Nanotechnology and Functional Materials,Uppsala University, one of several places where the interest of lignin in cosmetics is constantly growing. The functionalities of lignin have been studied to a great extent revealing its potential as a natural biopolymer to serve as a replacement for environmentally hazardous components in cosmetic formulations, namely UV-filters in sunscreens.
