ULTRASONIC DIAGNOSIS APPARATUS AND ULTRASONIC MEASUREMENT METHOD

摘要

Disclosed are an ultrasonic diagnosis apparatus and an ultrasonic measurement method enabling easy acquisition of elasticity information by means of a shear wave. The ultrasonic diagnosis apparatus is provided with an ultrasonic probe (4) for transmitting/receiving an ultrasonic wave to/from a subject (5), a vibrator (3) for generating a shear wave, a transmitting/receiving unit (2, 6) for transmitting/receiving an ultrasonic wave to/from the ultrasonic probe (4), a shear wave propagation detecting unit (14) for determining the propagation position of the shear wave and the propagation time of the shear wave, a shear wave image constructing unit (16) for constructing a shear wave image showing the relation between the propagation position and propagation time of the shear wave, and an elasticity information computing unit (15) for computing elasticity information on the basis of the boundary of the shear wave image.
