Abstract
A method and an apparatus for imaging blood motion by displaying an enhanced image of the fluctuating speckle pattern. The first step in the blood motion image processing is high-pass filtering of the signal vector from each range gate. Following high-pass filtering, a speckle signal is formed. The speckle signal is then subjected to a nonlinear scale conversion. The resulting speckle signal is displayed as the desired blood motion image concurrently with a corresponding tissue image.
