ABSTRACT:
An ultrasonic diagnostic apparatus preferable for creating a sharper image from the signal originating from contrast medium and the signal originating from biological tissues and an ultrasonic image display method are provided.The ultrasonic diagnostic apparatus comprises an ultrasonic probe10for transmitting/receiving ultrasonic waves to/from an object to be examined, transmission means12for providing drive signals to ultrasonic probe10, reception means for receiving the received signals outputted from ultrasonic probe10, signal processing means16for processing the received signals outputted from the receiving means14, image processing means18for constructing an ultrasonic image from the signals outputted from signal processing means16, and display means for displaying the ultrasonic image.Signal processing means16has means for detecting the signal intensity and the amount of variation with time of the received signal outputted from reception means14for each frequency band.Image processing means18has means for distinguishing the signal of the ultrasonic image originating from the contrast medium and the signal originating from the biological tissues.The signal intensity and the amount of variation with time of the received signal obtained by transmitting/receiving ultrasonic waves to/from the object are detected for each frequency band, the signals originating from the contrast medium and the biological tissues are distinguished on the basis of the signal intensity and the quantity of variation of time for each frequency band, and an ultrasonic image is displayed.
