A simulation approach was proposed to analyze the spectra of Doppler signals from stenoed artery in a steady flow, which can provide a useful guidance for detecting the formation understanding, diagnosis and treatment of many cardiovascular diseases. Firstly, by solving Navier-Stokes equations, the velocity distributions in the vessels with various stenoed degrees are calculated. Secondly, power spectral...
Simulation studies of Doppler ultrasound blood flow signals from intracranial aneurysms in a pulsatile flow can provide a useful guidance for detecting the formation and growth progress of the intracranial aneurysms using the Doppler ultrasound technology and forecasting the size of aneurysm. Firstly, blood flow velocity distribution in the area of Intracranial aneurysm is calculated by solving the...
