METHOD AND DEVICE FOR VISUALIZING MOVEMENT IN ULTRASONIC FLOW IMAGING USING PACKET DATA ACQUISITION

摘要

PROBLEM TO BE SOLVED: To provide a method and device for imaging blood movement by displaying an emphasized image of a fluctuating speckle pattern. SOLUTION: The first step of the blood movement image processing is high- pass filtering signal vectors from each range gate. After the high pass filtering, a speckle signal is formed. Then, the speckle signal receives non-linear scale conversion. The speckle signal, acquired as a result of the non-linear scale conversion, is displayed as a required blood movement image together with a corresponding tissue image.
