  1. 1. Annular dynamics of the human heart : novel echocardiographic approaches to assess ventricular function

    Författare :Carljohan Carlhäll; Neil B. Ingels Jr.; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The complex myocardial fiber architecture of the left ventricle (LV) enables long-axis motion (annular excursion), short-axis motion and also a small torsional deformation throughout the cardiac cycle. The contribution of the long-axis motion has proven to be important in generating ventricular filling and emptying, and the analysis of annular excursion has become a well established diagnostic tool for the assessment of ventricular function.

  3. 2. Automated Assessment of Blood Flow in the Cardiovascular System Using 4D Flow MRI

    Författare :Mariana Bustamante; Tino Ebbers; Carljohan Carlhäll; Petter Dyverfeldt; Michael Markl; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; 4D Flow MRI; Image Analysis; Segmentation;

    Sammanfattning : Medical image analysis focuses on the extraction of meaningful information from medical images in order to facilitate clinical assessment, diagnostics and treatment. Image processing techniques have gradually become an essential part of the modern health care system, a consequence of the continuous technological improvements and the availability of a variety of medical imaging techniques.

  4. 3. Towards Personalized Models of the Cardiovascular System Using 4D Flow MRI

    Författare :Belén Casas Garcia; Tino Ebbers; Jonas Lantz; Petter Dyverfeldt; Carljohan Carlhäll; Frans van de Vosse; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; 4D Flow MRI; Computational modelling; Blood flow; Hemodynamics;

    Sammanfattning : Current diagnostic tools for assessing cardiovascular disease mostly focus on measuring a given biomarker at a specific spatial location where an abnormality is suspected. However, as a result of the dynamic and complex nature of the cardiovascular system, the analysis of isolated biomarkers is generally not sufficient to characterize the pathological mechanisms behind a disease.

  5. 4. Blood flow specific assessment of ventricular function : Visualization and quantification using 4D flow CMR

    Författare :Alexandru Grigorescu Fredriksson; Carljohan Carlhäll; Bengt Johansson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The spectrum of cardiovascular diseases is the leading cause of morbidity and mortality globally. Early assessment and treatment of these conditions, acquired as well as congenital, is therefore of paramount importance. The human heart has a great ability to adapt to various hemodynamic conditions by cardiac remodeling.

  7. 5. Assessment of Ventricular Function in Normal and Failing Hearts Using 4D Flow CMR

    Författare :Jakub Zajac; Carljohan Carlhäll; Tino Ebbers; Petter Dyverfeldt; Victor A. Ferrari; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Heart failure is a common disorder and a major cause of illness and death in the population, creating an enormous health-care burden. It is a complex condition, representing the end-point of many cardiovascular diseases. LÄS MER
