  1. 1. Regional differences or similarities in human tooth biofilm microbiota: a pilot study

    Master-uppsats, Umeå universitet/Institutionen för odontologi

    Författare :Hanna Albertsson; Melina Isik; [2022]
    Nyckelord :bacteria oral microflora regional differences;

    Sammanfattning : Background: More than 700 oral bacterial species have been found and together they make out the oral microbiota. Specific species have shown to correlate with various oral diseases such as caries and periodontitis, but also systemic diseases. LÄS MER

  3. 2. Pediatric Brain Tumor Type Classification in MR Images Using Deep Learning

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Tamara Bianchessi; [2022]
    Nyckelord :pediatric brain tumors; MR image analysis; deep learning; classification; model explainability;

    Sammanfattning : Brain tumors present the second highest cause of death among pediatric cancers. About 60% are located in the posterior fossa region of the brain; among the most frequent types the ones considered for this project were astrocytomas, medulloblastomas, and ependymomas. LÄS MER

  4. 3. Body Ownership : An Activation Likelihood Estimation Meta-Analysis

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Martin Nilsson; [2020]
    Nyckelord :Body ownership; fMRI; ALE meta-analysis; Region of interest; Multisensory integration;

    Sammanfattning : How is it that we feel that we own our body? And how does the brain create this feeling? By manipulating the integration of multisensory signals, researchers have recently begun to probe this question. By creating the illusory experience of owning external body-parts and entire bodies, researchers have investigated the neurofunctional correlates of body ownership. LÄS MER

  5. 4. Multiband functional magnetic resonance imaging (fMRI) for functional connectivity assessments

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Cecilia Björnfot; [2018]
    Nyckelord :;

    Sammanfattning : During resting state the brain exhibits synchronized activity within all major brain networks. Using blood oxygen level dependent (BOLD) resting state functional magnetic resonance imaging (fMRI) based detection it is possible to quantify the degree of correlation, connectivity, between regions of interest and assess information regarding the integrity of the inter-regional functional integration.

  7. 5. Assessment of two optimization strategies for pediatric computed tomography examinations: Bismuth shielding & organ-based tube current modulation

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Sofia Skyttner; [2017]
    Nyckelord :Pediatric CT Computed Tomography Bismuth TCM tube current modulation optimization organ dose eye breast;

    Sammanfattning : Background: It is well known that pediatric patients are different from adult patients. Not only are children of a smaller physical size, but their anatomy differs as well. They are also more vulnerable to ionizing radiation than adults are, since their larger attributable life-time risk for cancer. LÄS MER
