  1. 1. Microfluidic flow splitter shape optimization for high throughput

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Christoffer Papamoustos Palmér; Joel Linder; [2023]
    Keywords : Genetic algorithms; Lab-on-a-chip; Optimization; Acoustofluidics; Microfluidics; Technology and Engineering;

    Abstract : Due to an increasing incidence rate, the need for new effective methods for diagnosing cancer are of high importance. Studies have shown that circulating tumor cells, CTCs, have great potential as a diagnostic biomarker. Acoustophoresis is a label free method, capable of separating CTCs from red blood cells in a blood sample. READ MORE

  3. 2. Generalized super-resolution of 4D Flow MRI : extending capabilities using ensemble learning

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Adam Hjalmarsson; Leon Ericsson; [2023]
    Keywords : 4D Flow MRI; Ensemble learning; Super-resolution; Machine learning; Neural networks; 4DFlowNet;

    Abstract : 4D Flow Magnet Resonance Imaging (4D Flow MRI) is a novel non-invasive technique for imaging of cardiovascular blood flow. However, when utilized as a stand-alone analysis method, 4D Flow MRI has certain limitations including limited spatial resolution and noise artefacts, motivating the application of dedicated post-processing tools.

  4. 3. Optimization-Based Geometry Correction Of Blood Flow CFD Simulations Using 4D-Flow Data

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Fritiof Hegardt; [2022]
    Keywords : Technology and Engineering;

    Abstract : 4D-flow is a powerful tool capable of capturing 3-dimensional, time-resolved flow measurements of blood flow in the body. Their current use is limited by resolution and scan times. A proposed solution is to use Simulation Based Imaging (SBI). READ MORE

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

    University essay from Linköpings universitet/Institutionen för hälsa, medicin och vård

    Author : Anthony van Oosten; [2022]
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 5. Boundary conditions at left ventricle wall for modelling trabeculae in blood flow simulations

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Lukas Werner; Ellen Leonardsson; [2022]
    Keywords : Trabeculae; CFD; Computational Fluid Dynamics; Hemodynamics; Blood Flow Simulations; Endocardial wall; porous; boundary conditions;

    Abstract : Heart disease is the main cause of death today, and studying causes and treatments are of great interest. Blood flow simulations using computational fluid dynamics shows promise in providing insight into this area. This study builds upon previous work by Larsson et al. and Kronborg et al. READ MORE
