The first real-time angle-independent velocity detection system for ultrasound has been constructed. The system detects both the axial and lateral components of velocity using the SAD algorithm, a novel time-domain method for tracking speckle patterns. In addition to quantifying 2D velocities, the system rejects echos according to absolute brightness and vectors according to a "best match" criterion, filters the flow image and presents the information as a color map to the physician each 30-50 milliseconds. This paper presents preliminary results along with an introduction to the system architecture, a discussion of clinical applications and an outline of future directions for the project.
