    • PURPOSE: An adaptively receiving beam focusing apparatus and a method are provided to reduce the distortion which is produced by CF unintentionally, by reducing the interference of other than purpose reflector inside the medium and the influence of noise. CONSTITUTION: A transducer(110) receives the ultrasonic signal reflected from photopoint. A delay offset application unit(140) applies the delay offset of each channel of the received ultrasonic signal to the received ultrasonic signal. A beam combiner(150) synthesizes the ultrasonic signal in which the delay time is compensated for each of the channel. The coefficient calculation unit(160) divides the aperture to a plurality of sub-aperture, and calculates the total coefficient which will be applied to the synthesized ultrasonic signal using the CF coefficient for each of the sub apertures. A coefficient application unit(170) applies the calculated total coefficient to the synthesized ultrasonic signal.
