| description | The subject of this paper is a new software simulating
ultrasound signal scattered on moving blood cells during Doppler examination of
blood flow velocity using pulsed technique. Generated data are used for
optimization and validation of Doppler signals processing algorithms. The
algorithm is based on the finite elements method FEM. A rigorous set of
postulates which simplifies physics of modeled phenomenon enables to quicken the
program significantly while preserving important properties (from application
point of view) of generated signal. The paper includes description of Doppler RF
signal generation algorithm. The simplifying postulates are listed together with
resulting signal fidelity degradation. Finally generated raw data is presented
together with its Doppler Audio and Color processed version. The signal
processing results enable to reconstruct correctly the velocity profile and its
time dependence. The results clearly confirm that the data generated by the
algorithm are suitable for Doppler signals processing. |
