  1. 21. Learning-based prediction, representation, and multimodal registration for bioimage processing

    Författare :Nicolas Pielawski; Carolina Wählby; Thomas Walter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deep learning; Multimodal image registration; bayesian optimization; Bioimage processing; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Microscopy and imaging are essential to understanding and exploring biology. Modern staining and imaging techniques generate large amounts of data resulting in the need for automated analysis approaches. LÄS MER

  3. 22. Segmentation and Visualisation of Human Brain Structures

    Författare :Roger Hult; Ewert Bengtsson; Lennart Thurfjell; Håkan Hall; Ingrid Agartz; Arvid Lundervold; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; segmentation; visualisation; brain; cortex; hippocampus; autoradiography; MRI; PET; ROI; Bildanalys; Image analysis; Bildanalys; Computerized Image Analysis; datoriserad bildanalys;

    Sammanfattning : In this thesis the focus is mainly on the development of segmentation techniques for human brain structures and of the visualisation of such structures. The images of the brain are both anatomical images (magnet resonance imaging (MRI) and autoradigraphy) and functional images that show blood flow (functional magnetic imaging (fMRI), positron emission tomography (PET), and single photon emission tomograpy (SPECT)).

  4. 23. Cervical Radiculopathy : Studies on Pain Analysis and Treatment

    Författare :Anna MacDowall; Claes Olerud; Helena Brisby; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cervical radiculopahy; Artificial disc replacement; Orthopaedics; Ortopedi;

    Sammanfattning : Background: Knowledge about how to interpret pain-analyzing tools such as the pain drawing test and the visual analog scale (VAS) in cervical spine patients are sparse; hence, they have never been validated for this subgroup of patients. The method of artificial disc replacement (ADR) has been developed as an alternative treatment to fusion surgery after decompression for cervical degenerative disc disease (DDD) with radiculopathy.

  5. 24. Deep Brain Stimulation Atlases in Movement Disorders : from Patient-Specific to Group Analysis

    Författare :Dorian Vogel; Karin Wårdell; Simone Hemm; Anders Eklund; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : deep brain stimulation (DBS) is an established method for symptom control in movement disorders such as Parkinson’s disease (PD) and essential tremor (ET). The treatment consists in delivering electrical stimulation in the deep brain via multi-contact electrodes. LÄS MER

  7. 25. On the necessity of screening and national registration of congenital cataracts

    Författare :Gunilla Magnusson; Göteborgs universitet; []
    Nyckelord :congenital cataract; glaucoma; intraocular surgery; posterior capsular opacification PCO ; prevalence; visual acuity VA ; visual impairment; screening; newborn examination; blindness prevention; cost-utility analysis; quality- adjusted life year QALY ;

    Sammanfattning : Objectives: The overall aim of this thesis was to contribute to improvements in the management of congenital cataract by defining the most efficient screening procedure, examining the magnitude of the morbidity rate, optimizing the timing of surgery by relating surgical outcome to age at intervention and severity of visual deprivation and furthermore by evaluating costs versus consequences of introducing the most efficient screening procedure found, on a national basis.Methods: Paper I: 72 children born between 1992 and 1998 in the Stockholm County Council region, Västra Götaland and Halland county, Linköping-Motala, Malmö, and Lund, who had surgery for congenital cataract before the age of one year were included in a retrospective study.
