ULTRASONIC IMAGING APPARATUS AND A METHOD FOR GENERATING AN ULTRASONIC IMAGE

摘要

A transmitter transmits ultrasonic waves to an object via an ultrasonic probe. A receiver receives echo signals reflected from the object via the ultrasonic probe. The receiver executes a delaying process on the echo signals in accordance with a plurality of set sound velocities for a delaying process, thereby generating a plurality of reception signals with different set sound velocities. An image generator generates a plurality of image data with the different set sound velocities based on the reception signals with the different set sound velocities. A contrast calculator obtains the contrast of each of the plurality of image data with the different set sound velocities. A selector selects image data with the highest contrast from among the plurality of image data. A display controller controls a display to display an image based on the image data selected by the selector.
