Abstract

Abstract: For simulating the Doppler ultrasound blood flow signals in the vessels with aneurysms at different stages of development, this paper presents a simulation model in which the Doppler ultrasound blood flow signals are obtained by employing cosine-superposed constituents which are modulated by a power spectral density (PSD) estimated from velocity profile calculated by analytically solving the Navier-Stokes equations according to the axis-centerline velocity at the upstream faraway segment of the aneurysms. In the experiments, the Doppler ultrasound blood flow signals in the normal vessels and vessels with aneurysms having different dilations are generated, respectively. The simulated Doppler ultrasound blood flow signals in the aneurysms have characteristics similar to those found in practice, and could be used as the detection algorithms for the occurrence and development of aneurysms disease.
