  1. 1. BLOOD FLOW DYNAMICS IN IDEALIZED MODEL OF LEFT ATRIUM USING FINITE ELEMENT ANALYSIS

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Marwin Haddad; Yonatan Noel Efrem; [2023]
    Keywords : finite element analysis; fluid mechanics; blood flow dynamics; cardiovascular anatomy;

    Abstract : Cardiovascular diseases, including heart failure, are a global health concern, necessitating advancements in non-invasive diagnostic tools and treatments. Computational modeling offers an invaluable approach to simulate and understand the intricacies of cardiac flow dynamics. READ MORE

  3. 2. Adaptation of existing cardiovascular simulation model to cardiac pumping physiology

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Emma Törner; [2017]
    Keywords : The CircAdapt model; biomedical modeling; cardiovascular; cardiac pumping; simulation; Technology and Engineering;

    Abstract : Cardiovascular diseases, affecting the heart and blood vessels, are the most common cause of death globally. However, the risk of suffering from a cardiovascular disease could decrease significantly as research improve treatment and identification of symptoms. READ MORE

  4. 3. Segmentation of the right ventricle in cardiac CT images

    University essay from Lunds universitet/Matematik LTH

    Author : Jesper Öberg; [2015]
    Keywords : Automatic; segmentation; endocardium; right ventricle; active shape model; Mathematics and Statistics;

    Abstract : Using cardiac computed tomography (CT), images of both the left and right ventricle can be acquired. Potential findings of interest are for example enlarged ventricles or inadequate pumping, which can be used for diagnosis. The analysis requires that the ventricles are outlined, either manually or automatically. READ MORE

  5. 4. Towards and Understanding of the Dynamics and Energy Efficiency of the Human Heart by Mathematical Modelling

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Patrik Hersenius; [2007]
    Keywords : Technology and Engineering;

    Abstract : This thesis is focused on modelling the pumping of the human heart. The modelling is limited to the left heart. Flows through the left heart were visualized by pathlines, streamlines and curl from 3D-velocity data acquired using 3D-velocity encoded magnetic resonance imaging (MRI). READ MORE

  6. 5. Investigation of transmural cardiac and fiber strain in ischemic and non-ischemic tissue during diastole

    University essay from Institutionen för medicinsk teknik

    Author : Katarina Lundgren; [2006]
    Keywords : strain; cardiac; fiber; transmural; ischemic; tensor; markers;

    Abstract : The cardiac wall has complex three-dimensional fiber structures and mechanical properties that enable the heart to efficiently pump the blood through the body. By studying the myocardial strains induced during diastole, information about the pumping performance of the heart and what mechanisms that are responsible for this effective blood filling, can be achieved.
