B-Flow - A new method for detecting blood flow

A new ultrasound-based blood flow detection method, B-Flow is introduced. T he amplitude, of scatterers in flowing blood is imaged by a subtraction mod e of two to four vectors along one line. Noise reduction is gained by using digital encoded US pulses. Signal enhancement is performed by using a puls e compression method (coded excitation). Compared to Color Doppler (CDI) Im aging B-Flow has a higher time (frame rate) and better spatial resolution. Typical CDI artifacts like color blooming or aliasing are missed. B-Flow do es not allow velocity measurements. B-Flow has its clinical value in imagin g perfused arterial vessels, simultaneous imaging of high and low Velocitie s and delineating plaque morphology with high resolution.
