Abstract
An ultrasonic diagnostic apparatus comprising an ultrasonic transmitting unit, an image signal generating unit and a signal addition unit. The ultrasonic transmitting unit transmits an ultrasonic wave having a wave surface except a plane wave surface and a focused focal wave surface to a subject so that shapes of wave surface portions change mutually in time on a same scanning line. The image signal generating unit receives reflected waves produced by the wave surface portions and generating image signals according to the reflected waves received. The signal addition unit obtains an image signal of which a speckle noise is reduced by adding the image signals mutually.
