Abstract
An ultrasonic measurement apparatus includes a transmission processing unit that performs processing for transmitting an ultrasonic wave at a given transmission angle, a reception processing unit that performs reception processing of an ultrasonic echo with respect to a transmitted ultrasonic wave, and a processing unit that performs processing with respect to a reception signal from the reception processing unit. The processing unit obtains a plurality of first resolution signals by synthesizing a plurality of the reception signals based on a first beamforming coefficient, and obtains a second beamforming coefficient for synthesizing a second resolution signal from the plurality of first resolution signals based on whether a signal processing target point belongs to a plane wave propagation region or belongs to a spherical wave propagation region.
