Title:
ULTRASONIC MEASUREMENT APPARATUS, ULTRASONIC IMAGE APPARATUS, AND ULTRASONIC MEASUREMENT METHOD
Document Type and Number:
Japanese Patent JP2015077393
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To obtain an image with higher resolution by applying adaptive beamforming to an ultrasonic measurement apparatus.SOLUTION: An ultrasonic measurement apparatus includes: a reception processing part which receives an ultrasonic echo for an ultrasonic wave transmitted to an object as a reception signal; a harmonic processing part which extracts a harmonic component of the ultrasonic echo from the reception signal; a signal processing part which performs weighted addition on the extracted harmonic component by using weight differentiated in accordance with the value of the extracted harmonic component; and an image generation part which generates an image on the basis of the signal subjected to the weighted addition.
