摘要： An ultrasonic flow mapping apparatus transmits and reflects waves from sampling points on a two-dimensional cross-section. The waves are detected while transmitting repeatedly ultrasonic pulses. The phase shifts of different reflected waves are calculated, and displayed in color to show a distribution of blood flow velocity. Artifact due to reflected waves from body organs, which remain even by using MTI filters, is detected from phase signals, which have not passed through the MTI filters, and the artifact is removed by lowering display brightness for a sampling point corresponding to a relevant detection output.
