Abstract

B-flow is a new technique that extends the resolution, frame rate, and dynamic range of B-mode to simultaneously image blood flow and tissue. B-flow relies on coded excitation to boost weak signals from blood scatterers and on tissue equalization to simultaneously display flowing blood and tissue without threshold decision and overlay. Various classes of codes such as Barker and Golay may be used. Clinical B-flow cineloops demonstrate 3× resolution and frame rate improvement over color flow, which, together with over 60 dB of display dynamic range, are able to image hemodynamics and vessel walls with unprecedented clarity
