ULTRASONIC MEASUREMENT APPARATUS, ULTRASONIC IMAGING APPARATUS, AND ULTRASONIC MEASUREMENT METHOD

摘要

An ultrasonic measurement apparatus includes a transmission processing unit that performs processing for transmitting an ultrasonic wave with respect to a target object, a reception processing unit that performs reception processing of an ultrasonic echo with respect to the transmitted ultrasonic wave, and a processing unit that performs processing with respect to a reception signal from the reception processing unit. The processing unit performs coupling coefficient specification processing of a plurality of first basis waves which configure the reception signal, with respect to the reception signal corresponding to a transmission pulse signal which is transmitted by the transmission processing unit. The processing unit performs conversion processing for converting the reception signal into a reconfiguration signal based on a plurality of coupling coefficients which are specified through the coupling coefficient specification processing, and a second basis wave having a wavenumber less than that of the first basis wave.
