Title:
ULTRASONIC MEASUREMENT APPARATUS, ULTRASONOGRAM APPARATUS, AND ULTRASONIC MEASUREMENT METHOD
Document Type and Number:
Japanese Patent JP2014147619
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 a high-resolution image with less artifacts even when the subject is moving.SOLUTION: An ultrasonic measurement apparatus 100 comprises a transmission processing unit 110, a reception processing unit 120, and a processing unit 130. The transmission processing unit 110 outputs a first transmission signal and a second transmission signal the phase of which is different by 180 degrees from the phase of the first transmission signal. The reception processing unit 120 outputs a first received signal by performing reception processing of a first ultrasonic echo in response to the first transmission signal, and outputs a second received signal by performing reception processing of a second ultrasonic echo in response to the second transmission signal. The processing unit 130 performs detection processing of a change in the positional relationship between a subject and an ultrasonic probe on the basis of the first received signal and the second received signal, and determines which of a filter method and a phase inversion method is used as a harmonic component extraction method on the basis of the detection processing result.
