The diagram of R-Flow

Caption

Ultrafast plane-wave ultrasound imaging is used to acquire beamformed in-phase and quadrature (IQ) data (A), followed by clutter filtering to extract blood flow signals. Spatiotemporal image slices (x–t and z–t planes) are constructed (B and C), from which lateral and axial velocity components are estimated via Radon transform (D and E), respectively. For lateral flow estimation, axial flow motion compensation is applied to enhance the continuity of red blood cell trajectories in x–t plane (C). R-Flow yields blood flow velocity maps, as well as axial and lateral velocity dynamics (F).
