Title:
ULTRASONIC MEASUREMENT APPARATUS, ULTRASONOGRAM APPARATUS, AND ULTRASONIC MEASUREMENT METHOD
Document Type and Number:
Japanese Patent JP2014147620
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ultrasonic measurement apparatus, an ultrasonogram apparatus, an ultrasonic measurement method, and the like capable of generating an image with less artifacts (false image noises) without causing deterioration of time resolution even when the subject is moving.SOLUTION: An ultrasonic measurement apparatus 100 comprises: a transmission processing unit 110 for performing processing to send one or more ultrasonic waves to a subject; a reception processing unit 120 for performing reception processing of the ultrasonic echoes in response to the sent ultrasonic waves; and a processing unit 130 for performing processing of a received signal from the reception processing unit 120. The processing unit 130 generates a first separation signal and a second separation signal, the phase of which is different by 180 degrees from the phase of the first separation signal, from received signals, and performs addition processing or subtraction processing between the first and second separation signals to extract the harmonic components of the ultrasonic echoes.
