PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus which can effectively emphasize a contrast echo component to a tissue echo component. SOLUTION: In an ultrasonic diagnostic apparatus wherein based on an echo signal obtd. by injecting a contrast medium into a subject and scanning with ultrasonic wave, ultrasonic information is obtd., a band passing type filter 9 for extracting a higher harmonic component from the echo signal and a band removing type filter 10 for suppressing a specified band component from the extracted higher harmonic component in order to emphasize a contrast echo component by the contrast effect of the contrast medium, are provided. |
