  1. 1. Mitralisregurgitation hos australian kelpie : myxomatös mitralisklaffsjukdom eller annan orsak?

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Eddie Leão Sjöblom; [2023]
    Nyckelord :Myxomatös klaffsjukdom; MMVD; mitralisregurgitation; australian kelpie; blåsljud; LVIDD;

    Sammanfattning : Myxomatös mitralisklaffsjukdom (MMVD) är en förvärvad hjärtsjukdom som är vanlig bland hundar, särskilt hos mindre raser såsom cavalier king charles spaniel, taxar och toyraser. Sjukdomen leder till en förtjockning och prolaps av klaffarna, vanligtvis mitralisklaffen, som börjar läcka blod från kammaren till förmaket (mitralisregurgitation). LÄS MER

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

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

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

    Sammanfattning : 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. LÄS MER

  4. 3. Semi-Automatic Analysis and Visualization of Cardiac 4D Flow CT

    Master-uppsats, Linköpings universitet/Institutionen för hälsa, medicin och vård

    Författare :Anthony van Oosten; [2022]
    Nyckelord :4D CT; CT; 4D flow; Flow Component Analysis; Singular value decomposition; left atrial appendage; LAA; CFD; 3 chamber view; computed tomography; maximum outflow velocity; volume rendered CT; semi-automatic; visualization; flow visualization; cardiac views; semi-automatic analysis; semi-automatic visualization; visualization of 4D flow;

    Sammanfattning : The data obtained from computational fluid dynamics (CFD) simulations of blood flow in the heart is plentiful, and processing this data takes time and the procedure for that is not straightforward. This project aims to develop a tool that can semi-automatically process CFD simulation data, which is based on 4D flow computed tomography (CT) data, with minimal user input. LÄS MER

  5. 4. Left atrial strain and 3-dimensional volume measurements of the left atrium : alternative methods for detecting diastolic dysfunction

    Magister-uppsats, Uppsala universitet/Institutionen för kvinnors och barns hälsa

    Författare :Fanny Nilsson; [2022]
    Nyckelord :LA-strain; Diastolic dysfunction; echocardiography; Philips; 3D-measurements; Vänster förmaksstrain; diastolisk dysfunktion; ekokardiografi; Philips; 3D-mätning;

    Sammanfattning : Heart failure with preserved ejection fraction has its main pathophysiology in the diastolic dysfunction which is characterized by increased filling pressures. This can be discovered during a routinely performed echocardiographic examination. LÄS MER

  7. 5. Segmenting the Left Atrium in Cardic CT Images using Deep Learning

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Aman Kumar Nayak; [2021]
    Nyckelord :Deep Learning; UNet; Image Segmentation;

    Sammanfattning : Convolution neural networks have achieved a state of the art accuracy for multi-class segmentation in biomedical image science. In this thesis, a 2-Stage binary 2D UNet and MultiResUNet are used to segment the 3D cardiac CT Volumes. 3D volumes have been sliced into 2D images. LÄS MER
