Abstract
An ultrasonic imaging apparatus having a depth range setter for setting a threshold value of detection level for a Doppler signal in an ultrasonic circuit unit , a unit for extracting a time at which the Doppler signal exceeds the set detection level and a signal level in excess of the set detection level, and a ROI depth data generator for determining, for an adaptive phase controller , a ROI depth range for correction necessary to make echo signals of neighboring channels be in phase by using the extracted time and signal level, whereby the focal point can follow the ROI region in an object to be inspected by correcting echo signals from the region where the intensity of the Doppler signal reaches the detection level or its neighboring region so as to make them be in phase between adjacent transducers.
