A Technique to Track Scatterers for Continuous High-speed Plane-wave Ultrasound Simulations based on a Fluid Domain Model.

ABSTRACT: Ultrasound simulations of blood flow are useful to evaluate or optimize new transmit schemes, transducer geometries, or post processing methods such as vector flow. In cases of complex flow, a flow domain model (FDM) is often used to define the time history of the velocity field. Scatterers representing blood cells are seeded in the flow field and their positions are updated each time step after spatial and temporal interpolation of the FDM velocity field. At each time step, the scatterers are passed to an ultrasound simulator to generate synthetic ultrasound backscatter data. Here, a technique is described to continuously track, without temporal discontinuities, a stable concentration of scatterers representing complex flow with reverse, rotational, out-of-plane and/or helical features.
