Patent ID: 8708910

Claim:
An ultrasonic diagnosis apparatus comprising: an ultrasonic probe including a plurality of ultrasonic transducers configured to transmit ultrasonic waves to an object, receive the ultrasonic waves reflected by the object, and output ultrasonic detection signals; a reception time calculating device configured to calculate at least one of a reception time and a reception wave at each of the plurality of ultrasonic transducers corresponding to a shallower point of two or more points whose positions along a depth direction of the object are different from each other; an image generating device configured to generate an image at the two or more points, based on a hypothetical sound velocity set in a region including the two or more points and the calculated one of the reception time and the reception wave; an image analyzing device configure to perform an image analysis of the generated image; and a local sound velocity calculating device configured to calculate a local sound velocity in the region including the two or more points, based on a result of the image analysis.
