ULTRASOUND DIAGNOSIS APPARATUS AND CONTROL METHOD

摘要

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.

1. An ultrasound diagnosis apparatus comprising:
a transmitter/receiver configured to transmit, at least once in each scanning line, a first ultrasound pulse and a second ultrasound pulse, whose amplitude is equivalent to amplitude which is acquired by modulating amplitude of the first ultrasound pulse by using a given ratio, and acquire a received-signal group consisting of multiple received signals based on the transmitting; a signal processor configured to, 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 a first received signal group acquired by the transmitter/receiver, acquire 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; and an image generator configured to generate an ultrasound image based on the second composite signal.
