Endovascular stent has an increasingly important application in the treatment of aneurysms. This study is to simulate Doppler ultrasound blood flow signals from a stented sidewall aneurysm based on a computational fluid dynamics model. For comparisons, a stented and non-stented sidewall aneurysm models are constructed respectively. Firstly the blood flow velocity distribution in the area of the sidewall...
Hemodynamic parameters of the pulmonary circulation are important reference factors in the diagnoses and treatments of children 's cardiovascular diseases. These parameters are usually measured by the cardiac catheterization. Recently several noninvasive methods have been proposed to estimate these parameters using the ultrasound technique. In order to execute the noninvasive estimation automatically,...
