Abstract:
A diagnostic ultrasound apparatus comprising:a transmitter/receiver configured to repeatedly scan a cross section of an object at intervals by transmitting a wideband ultrasound pulse along each raster on the cross section and receiving an echo signal reflected from the object in response to the transmitted ultrasound pulse; a B-mode image processor configured to produce a B-mode image of the cross section from the received echo signal; a processor configured to obtain an analytic value of a moving-element signal in the cross section using the received echo signal reflected, each time of the scanning, from each sample point along each raster on the cross section, the analytic value including a power value of the moving-element signal at each sample point on the cross section; and an image synthesizer configured to make a two-dimensional image composed of the B-mode image on which the analytic value is two-dimensionally mapped.
