  1. 1. Simulating metal ct artefacts for ground truth generation in deep learning.

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Arthur Barakat; [2023]
    Keywords : Technology and Engineering;

    Abstract : CT scanning stands as one of the most employed imaging techniques used in clinical field. In the presence of metal implants in the field of view (FOV), distortions and noise appear on the 3D image leading to inaccurate bone segmentation, often required for surgery planning or implant design.

  3. 2. Machine learning-assisted image analysis and metabarcoding for monitoring of plankton in the seas surrounding Sweden

    University essay from KTH/Industriell bioteknologi

    Author : Karin Garefelt; [2023]
    Keywords : Imaging FlowCytobot; imaging-in-flow cytometry; plankton imaging; convolutional neural network; metabarcoding; Imaging FlowCytobot; flödesmikroskopi; övervakning av plankton; konvolutionella neuronnät; DNA-streckkodning;

    Abstract : I miljöövervakningen av haven runt Sverige har manuell mikroskopi av plankton länge varit den huvudsakliga tekniken för att övervaka växtplanktonbestånden och algblomningar. Nya tekniker utvärderas, men det är inte känt hur resultaten från de nyare teknikerna relaterar till varandra. READ MORE

  4. 3. Reconstruction of Accelerated Cardiovascular MRI data

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Hussnain Khalid; [2023]

  5. 4. Predictive MR Image Generation for Alzheimer’s Disease and Normal Aging Using Diffeomorphic Registration

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yuqi Zheng; [2023]
    Keywords : Medical Image Generation; Brain Aging; Diffeomorphic Registration; AlzheimerŠs Disease; Medicinsk bildgenerering; Åldrande av hjärnan; DiffeomorĄsk registrering; Alzheimers sjukdom;

    Abstract : Alzheimer´s Disease (AD) is the most prevalent cause of dementia, signifying a progressive and degenerative brain disorder that causes cognitive function deterioration including memory loss, communication difficulties, impaired judgment, and changes in behavior and personality. Compared to normal aging, AD introduces more profound cognitive impairments and brain morphology changes. READ MORE

  6. 5. The role of word accents in semantic processing in South Swedish

    University essay from Lunds universitet/Masterprogram: Språk och språkvetenskap; Lunds universitet/Fonetik

    Author : Jinhee Kwon; [2023]
    Keywords : Word accents; spoken word recognition; prediction; ERP; N400; Languages and Literatures;

    Abstract : Prosodic cues can aid speech processing by adding semantic information in lexical tones or functional information in intonational tones. Swedish word accents are considered to have stronger grammatical functions than semantic roles, although they are shaped by both lexical and intonational information structure. READ MORE
