A time delay unit 2 for delaying receiving signals from a probe 1, an adder unit 3 for adding outputs of the time delay unit 2 and forming ultrasonic beam, a phase difference computing unit 5 for computing phase differences between signals and a correlation factor computing unit 6 for computing correlation factors are provided, the outputs of the correlation factor computing unit 6 are compared with values of a correlation factor storage unit 8 by a correlation factor comparing unit 9, and when the former is larger than the latter, the outputs of the phase difference computing unit 5 and the outputs of the correlation factor computing unit 6 are respectively stored in a phase difference storage unit 7 and the correlation factor storage unit 8, and at the moment when all of the phase difference computations have been completed, the time delay unit 2 is controlled by making use of the value stored in the phase difference storage unit 7. The phase difference computations and the correlation factor computations are complex number computation, and only when the real part of a complex number which is an object for the phase difference computation is positive, a sign judging unit 10 issues an operation command to the correlation factor comparing unit 9.

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.
