  1. 1. 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

  2. 2. 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.

  3. 3. 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

  4. 4. On the Construction of an Automatic Traffic Sign Recognition System

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Fredrik Jonsson; [2017]
    Nyckelord :traffic sign recognition; object detection; image classification; mixture models; Gibbs sampling;

    Sammanfattning : This thesis proposes an automatic road sign recognition system, including all steps from the initial detection of road signs from a digital image to the final recognition step that determines the class of the sign. We develop a Bayesian approach for image segmentation in the detection step using colour information in the HSV (Hue, Saturation and Value) colour space. LÄS MER

  5. 5. Accuracy of Quantification for Renography with 99mTc-MAG3: A Study on Virtual and Clinical Data

    Master-uppsats, Lunds universitet/Medicinsk strålningsfysik, Lund

    Författare :Irma Ceric; [2016]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Aim: Renography with 99mTc-MAG3 is one of the most common nuclear medicine examinations. It’s extensive use justifies a thorough investigation of the methods used to accurately determine the split renal function, for instance with regard to background subtraction and correction for renal depth differ- ences.
