  1. 1. The functional anatomy of the crocodilian heart

    University essay from Linköpings universitet/Biologi

    Author : Jennifer Karlsson; [2023]
    Keywords : Anatomy; Cardiac right-to-left shunt; Cog-teeth-like valves; Crocodilian heart; Foramen of Panizza; Hemodynamics; Left aorta;

    Abstract : Crocodiles are ectothermic, intermittent breathing reptiles with low metabolic rates. Additionally, they are diving animals that can stay submerged for long periods, which poses special demands on their cardiovascular system. The crocodilian heart is four-chambered with completely separated ventricles, making it unique among other reptiles. READ MORE

  3. 2. Deep learning for temporal super-resolution of 4D Flow MRI

    University essay from KTH/Matematik (Avd.)

    Author : Pia Callmer; [2023]
    Keywords : Temporal super-resolution; 4D Flow MRI; CNN; Artificial Intelligence; MRI; 4D flow; Temporal superupplösning; 4D flöde MRI; CNN; artificiell intelligens; MRI; 4D-flöde;

    Abstract : The accurate assessment of hemodynamics and its parameters play an important role when diagnosing cardiovascular diseases. In this context, 4D Flow Magnetic Resonance Imaging (4D Flow MRI) is a non-invasive measurement technique that facilitates hemodynamic parameter assessment as well as quantitative and qualitative analysis of three-directional flow over time.

  4. 3. Deep Learning for Prediction of Falling Blood Pressure During Surgery : Prediction of Falling Blood Pressure

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Navid Zandpour; [2022]
    Keywords : Arterial Blood Pressure; Convolutional Neural Network; Supervised Learning; Hypotension; Prediction; Arteriellt Blodtryck; Faltningsnätverk; Övervakad Inlärning; Hypotension; Prediktion;

    Abstract : Perioperative hypotension corresponds to critically low blood pressure events during the pre, intra and postoperative periods. It is a common side effect of general anaesthesia and is strongly associated with an increased risk of postoperative complications, such as acute kidney injury, myocardial injury and in the worst case death.

  5. 4. Patient simulation. : Generation of a machine learning “inverse” digital twin.

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Paolo Calderaro; [2022]
    Keywords : Machine learning; Cardiovascular models; Multi-variate time series; Multitarget regression; Inverse modelling; Maskininlärning; kardiovaskuläramodeller; multivariatatidsserier; multi-target regression; invers modellering;

    Abstract : In the medtech industry models of the cardiiovascular systems and simulations are valuable tools for the development of new products ad therapies. The simulator Aplysia has been developed over several decade and is able to replicate a wide range of phenomena involved in the physiology and pathophysiology of breathing and circulation. 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
