B-flow

B-flow was developed by GE using coded excitation.  

Based on the GE-patented Digitally Encoded Ultrasound technique to digitally suppress unwanted signals (e.g. noise and tissue) and boost weak signals (e.g. blood echoes), B-Flow helps overcome the limitations of Doppler with the following imaging benefits:

• Direct hemodynamics visualization

• No vessel wall overlap (the flow does not overwrite the vessel wall)

• Less dependency on the user or scanning angle

• Higher frame rate and spatial resolution than Color Flow
