摘要
According to the present invention, a method for reducing a sidelobe in an ultrasound image includes Step 1 of receiving, from individual receiving elements of an array transducer, ultrasonic signals reflected from an imaging point, and outputting the ultrasonic signals as channel signals of the corresponding receiving elements; Step 2 of applying focusing delays to each of the channel signals to temporally align the channel signals; and Step 3 of synthesizing an ultrasound image by using an added-up signal which is obtained by adding up the temporally aligned channel signals, wherein Step 3 includes calculating a magnitude of a corresponding sidelobe signal by using a spatial frequency of the sidelobe signal which generates a sidelobe and the number of receiving elements and synthesizing the ultrasound image by subtracting the calculated magnitude of the sidelobe signal from the added-up signal.
