Title:

APPARATUS AND METHOD FOR ADAPTIVE RECEPTION BEAM FOCUSING

Document Type and Number:

WIPO Patent Application WO/2013/018964

Kind Code:

A1

Abstract:

The present invention relates to an apparatus for adaptive reception beam focusing, comprising: a transducer which receives an ultrasonic wave signal reflected from an image point; a delay offset application unit which calculates a delay time of a received ultrasonic wave signal, and applies a delay offset for each channel of the received ultrasonic wave signal to the received ultrasonic wave signal; a beam synthesis unit which synthesizes the ultrasonic wave signal, which has been compensated for a delay time of each channel; a coefficient calculation unit which divides an aperture into a plurality of sub-apertures, and then calculates an entire coefficient to be applied to the synthesized ultrasonic wave signal using CF coefficients according to the sub-apertures; and a coefficient application unit which applies the calculated entire coefficient to the synthesized ultrasonic wave signal, thereby reducing errors when the existence of an interference point in the vicinity of an image point causes a reception signal reflected from the image point to be overlapped with a reception signal reflected from the interference point.
