Vector Flow Imaging (VFI) provides a multidimensional, angle-independent estimation of blood flow velocity, allowing detailed dynamic visualization of complex and transient flow events.
Vector Flow Imaging provides an angle-independent, multidimensional estimation of blood flow velocity, offering detailed dynamic visualization of complex flow compared to conventional Doppler.
Doppler ultrasonography is routinely used to identify abnormal blood flow. Nevertheless, conventional Doppler can be used to determine only the axial component of blood flow velocity and is angle dependent. A new method of multidimensional angle-independent estimation of flow velocity, called Vector Flow Imaging (VFI), has been proposed. It quantitatively evaluates the true velocity vector's amplitude and direction at any location into a vessel and displays a more intuitive depiction of the flow movements. High frame rate VFI, based on plane wave imaging, allows a detailed dynamic visualization of complex flow by showing even transient events, otherwise undetectable.

Goddi et al. (2017) conducted a review in Abnormal blood flow. Vector Flow Imaging (VFI) vs. Conventional Doppler ultrasonography was evaluated. Vector Flow Imaging (VFI) provides a multidimensional, angle-independent estimation of blood flow velocity, allowing detailed dynamic visualization of complex and transient flow events.
