PROBLEM TO BE SOLVED: To set not only timewise but also spatially optimum filter characteristics. SOLUTION: This device is provided with a reception system 3 for obtaining reception signals including phase information and amplitude information from reflected wave signals obtained by scanning the cross section of a testee body by ultrasonic waves, a detector 4 for generating ultrasonic images based on at least one of the phase information and the amplitude information included in the reception signals, a display unit 7 for displaying the ultrasonic images and an inter-frame filter part 9 provided between the reception system 3 and the detector 4 for using the time sequential reception signals relating to respective plural points inside the cross section and attenuating a specified frequency component. |
