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

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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Quantification of cerebral blood flow with 15O-water PET : A comparison study between PET/CT and PET/MR and two different blood sampling instruments

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik; Umeå universitet/Diagnostisk radiologi

    Författare :Amanda Eriksson; [2021]
    Nyckelord :Cerebral Blood Flow; CBF; oxygen-15-labelled water; PET CT; PET MR; Quantification of CBF; Image Derived Input Function; IDIF; Blood Sampled Input Function; BSIF; Arterial Input Function; AIF; Tracer Kinetic Modelling; Single Tissue Compartmental Model; 1TCM;

    Sammanfattning : Cerebral blood flow quantification is a vital diagnostic tool for disease monitoring and used for diagnosing a variation of pathological conditions. The human brain requires roughly about 20 % of the total cardiac output to sustain normal functioning, hence the perfusion of blood is an important factor to deliver oxygenated blood. LÄS MER

  4. 3. Modelling development of ECMO return flow in bifurcating arteries

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Friederike Schäfer; [2021]
    Nyckelord :Fluid Mechanics; CFD; ECMO;

    Sammanfattning : Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is a life saving therapy for critically ill patients experiencing a heart and lung failure. During this therapy, a common complication is limb ischemia in the leg where the return cannula reintroduces the oxygenated blood to the patient. LÄS MER

  5. 4. Development of innovative multi-physics solutions to optimize biological measure performance

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Mathilde Aubret; [2020]
    Nyckelord :Camera variability; statistics; image processing; LFIA; microfluidic; modelling;

    Sammanfattning : Paper strips are becoming widely used for blood testing and particularly with embedded immunoassays. Among the so called "Point of Care" devices, the association of LFIA tests with a reading technology able to capture the strip and analyze its composition to output the biological result is advantageous in many ways.

  7. 5. Heat detection in precurser of tennis elbow and other joint injuries

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Olivia Paulsson; [2020]
    Nyckelord :Inflammation; tendons; thermometers; heat transfer; modelling; Inflammation; senor; termometer; värmetransport; modellering;

    Sammanfattning : Background: Joint injuries are a complex matter. Due to the low blood flow to the tendons and ligaments, they take months or even years to heal; some fail to heal. This can be devastating for the elite athlete as well as for the labour worker or everyday person. LÄS MER
