SUBJECT INFORMATION ACQUISITION APPARATUS, SUBJECT INFORMATION ACQUISITION METHOD, AND PROGRAM

摘要

With unwanted reflected waves, an error might be produced in a movement velocity detection of a measurement object. There is provided a subject information acquisition apparatus including a plurality of transducers configured to transmit an acoustic wave pulse to a subject, receive reflected waves reflected from a plurality of positions in the subject, and convert the reflected waves respectively into time series received signals and a processing unit configured to acquire movement information of the object by using a plurality of the received signals output from the plurality of transducers are provided. The processing unit extracts a plurality of signals each representing a movement component by using the plurality of received signals, performs adaptive signal processing by using the plurality of signals each representing a movement component, and acquires the movement information of the object by using a plurality of output signals obtained by the adaptive signal processing.
