    Sammanfattning : The construction industry faces common challenges in managing project information andcommunication, with a lack of communication costing the industry up to 60 billion SEKannually. To address these issues and improve efficiency, the industry has begunimplementing a digital approach, exemplified by Building Information Modelling (BIM). LÄS MER

  4. 3. Inclusion of more sources in a commercial brachytherapy Monte Carlo

    Kandidat-uppsats,

    Författare :Philip Wiman; Emil Forsberg; Robin Vestling; [2023]
    Nyckelord :;

    Sammanfattning : Brachytherapy is a cancer treatment method where a solid radioactive source is placed inside the body in order to target cancer cells with a high dose of radiation while minimizing damage to surrounding healthy tissue. The most common method for treatment planning in brachytherapy is the TG43 formalism where the whole patient geometry is treated as water. LÄS MER

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

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fritiof Hegardt; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 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). LÄS MER

  7. 5. Exploring Deep Learning Frameworks for Multiclass Segmentation of 4D Cardiac Computed Tomography

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

    Författare :Norman Janurberg; Christian Luksitch; [2021]
    Nyckelord :Computed Tomography; Multiclass Segmentation; Image Segmentation; 4D; Deep Learning; MONAI; Unet; Cropping network; Multiaxis Segmentation;

    Sammanfattning : By combining computed tomography data with computational fluid dynamics, the cardiac hemodynamics of a patient can be assessed for diagnosis and treatment of cardiac disease. The advantage of computed tomography over other medical imaging modalities is its capability of producing detailed high resolution images containing geometric measurements relevant to the simulation of cardiac blood flow.
