ABSTRACT:
An ultrasonic imaging system includes an ultrasonic probe for transmitting and receiving an ultrasonic wave, a driver unit for driving the ultrasonic probe, a detector unit for detecting an echo signal received by the ultrasonic probe, a filter unit operative to pass a detection signal from the detector unit and having a plurality of passbands which have respective flat frequency response characteristics and respective gains different from each other, a scanning conversion unit for converting the detection signal, which has passed through the filter unit, to a display signal to be displayed on a television, etc., and a display unit receiving the display signal from the scanning conversion unit to display it as a tomographic image. The filter unit operates to decrease respective amplitudes of high frequency components contained in the detection signal and to reduce a difference in brightness between adjacent scanning lines of the display unit, and flat frequency response characteristics of the filter unit prevent deterioration of frequency response characteristics of the detection signal. This makes it possible to produce a tomographic image of high resolution up to the resolution limit of the scanning lines of the display unit without impairing the image quality.
