Abstract

An ultrasound diagnosis apparatus includes a transmitter/receiver, a signal processor, and an image generator. The transmitter/receiver transmits, at least once in each scanning line, a first ultrasound pulse and a second ultrasound pulse whose amplitude corresponds to amplitude of the first ultrasound pulse modulated at a given ratio and acquires a received-signal group consisting of multiple received signals. The signal processor acquires, on the basis of a coefficient that reduces the energy of a first composite signal that is obtained by combining, in accordance with the given ratio, multiple received signals contained in the first received signal group acquired by the transmitter/receiver, a second composite signal by combining multiple received signals contained in a second received signal group that is acquired by the transmitter/receiver and that is different from the first received signal group. The image generator generates an ultrasound image based on the second composite signal.
