  1. 1. Automatic segmentation in CMR - Development and validation of algorithms for left ventricular function, myocardium at risk and myocardial infarction

    Författare :Jane Tufvesson; Lund Klinisk fysiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic segmentation; cardiovascular magnetic resonance; validation; Expectation Maximization; freely available software; myocardial infarction;

    Sammanfattning : In this thesis four new algorithms are presented for automatic segmentation in cardiovascular magnetic resonance (CMR); automatic segmentation of the left ventricle, myocardial infarction, and myocardium at risk in two different image types. All four algorithms were implemented in freely available software for image analysis and were validated against reference delineations with a low bias and high regional agreement. LÄS MER

  3. 2. The Potential and Challenges of the Use of Dynamic Software in Upper Secondary Mathematics : Students’ and Teachers’ Work with Integrals in GeoGebra Based Environments

    Författare :Sanela Mehanovic; Per Jönsson; Morten Blomhøj; Per-Eskil Persson; Morten Misfeldt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : An introduction of computer software into mathematics classrooms makes the didactical situation more complex compared with previous learning environments (Blomhøj, 2005). A technological tool becoming a mathematic work tool in the hands of the students is a process that has turned up unexpectedly complex (Artigue, 2002). LÄS MER

  4. 3. Disease surveillance systems

    Författare :Baki Cakici; Magnus Boman; Stefan Johansson; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; disease surveillance; syndromic surveillance; outbreak detection; health informatics; computer science; Health and medical services in society; Hälso- och sjukvård i samhället; Epidemiology; Epidemiologi; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : Recent advances in information and communication technologies have made the development and operation of complex disease surveillance systems technically feasible, and many systems have been proposed to interpret diverse data sources for health-related signals. Implementing these systems for daily use and efficiently interpreting their output, however, remains a technical challenge. LÄS MER

  5. 4. Echocardiography in myocardial infarction : aspects on diastolic function and evaluation by cardiovascular magnetic resonance imaging

    Författare :Martin G Sundqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Echocardiography is routinely used to evaluate patients with known or suspected myocardial infarction (MI). Cardiovascular magnetic resonance imaging (CMR) provides the ability to quantify myocardial infarction size (IS), and to establish an underlying diagnosis in MI cases with nonobstructive coronary arteries (MINOCA).

  7. 5. Functional analysis of genetic risk markers

    Författare :Jesper Robert Gådin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Regulatory variants are the main factors responsible for genetic predisposition to how e.g. humans react differently to the environment. LÄS MER
