1. 6. Analyzing arterial blood flow by simulation of bifurcation trees

   University essay from Linköpings universitet/Matematik och tillämpad matematik

   Author : Johan Ottosson; [2019]
   Keywords : Arterial blood flow; Blood flow modelling; bifurcation tree; simulation; fixed-point iteration;

   Abstract : The flow of blood in the human body is a very important component in un-derstanding a number of different ailments such as atherosclerosis and a falseaneurysm. In this thesis, we have utilized Poiseuille’s solution to Navier-Stokesequations with a Newtonian, incompressible fluid flowing laminar with zero ac-celeration in a pipe with non-flexible walls in order to study blood flow in anarterial tree.

3. 7. Modelling of the mechanobiological adaptation to vascular occlusion in the arterial tree

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Jaime Rodríguez María; [2016]
   Keywords : Vascular occlusion; modelling; arteries; arterial tree; growth and remodelling; Murray; cerebrocardiovascular diseases; adaptation; thrombosis; calcification; anemia; polycythemia; isquemia; edema; Oclusión vascular; modelado; arterias; árbol arterial; crecimiento y remodelado; Murray; enfermedades cerebrocardiovasculares; adaptación; trombosis; calcificación; anemia; policitemia; isquemia; edema;

   Abstract : It is known that there are many cardiovascular diseases caused by the alterations in the blood vessels, that affect most of the world population. The knowledge of the mechanobiological behavior of blood vessels is used for understanding how cardiovascular diseases could affect the human body. READ MORE

4. 8. Development of a pipeline for patientspecific finite element modelling of the left ventricle of the human heart

   University essay from KTH/Numerisk analys, NA

   Author : Mbah Chrameh Fru; [2014]
   Keywords : ;

   Abstract : In order to perform simulations of the human heart using a heart finite element solver developed at the Computational Technology Laboratory at KTH with a data set provided by Philips consisting of surface meshes of a whole heart, the surface mesh has to be converted to a volume mesh. The conversion is manual and time consuming. READ MORE

5. 9. Feasibility Study of Phase Measurements of the Arterial Input Function in Dynamic Contrast Enhanced MRI

   University essay from Radiofysik

   Author : Sandra Marklund; [2009]
   Keywords : AIF; Arterial Input Function; DCE-MRI; Dynamic Contrast Enhanced MRI; MRI; Gd; Gadolinium; Phase measurement; Phase;

   Abstract :   Acquired data from dynamic contrast enhanced MRI measurements can be used to non-invasively assess tumour vascular characteristics through pharmacokinetic modelling. The modelling requires an arterial input function which is the concentration of contrast agent in the blood reaching the volume of interest as a function of time. READ MORE

6. 10. Radio Frequency Thermal Treatment of Liver Tumours : -Influence of Blood Perfusion and Large Vessels

   University essay from Institutionen för ekonomisk och industriell utveckling

   Author : Per Andersson; [2008]
   Keywords : Radio Frequency Ablation; Hepathic tumours; FEM; Modelling; Simulation;

   Abstract : Radio frequency ablation (RFA) is a commonly used minimally invasive method of treating liver cancer tumours which utilises RF current for heating tumour tissue up to a lethal temperature. RF current is generated by a power generator and applied to the tumour by an electrode which is inserted into the tumour either during percutaneous or open surgery. READ MORE
