Ultrasonic image boundary extracting method, ultrasonic image boundary extracting apparatus, and ultrasonic imaging apparatus
First Claim
1. An ultrasonic image boundary extracting method comprising the steps of:
- (a) obtaining an interrelationship among plural reception signals with respect to a region within an object to be inspected from among reception signals obtained by transmitting ultrasonic waves toward the object from plural ultrasonic transducers and receiving ultrasonic waves reflected from the object; and
(b) detecting a boundary between plural different tissues within the object based on said interrelationship to thereby generate information on a tissue boundary.

Abstract
An ultrasonic image boundary extracting apparatus capable of accurately extracting outlines of tissues based on reception signals respectively output from ultrasonic transducers by receiving ultrasonic echoes. The ultrasonic image boundary extracting apparatus includes: an analysis unit for obtaining an interrelationship among plural reception signals with respect to a region within an object to be inspected from among reception signals obtained by transmitting ultrasonic waves toward the object from plural ultrasonic transducers and receiving ultrasonic waves reflected from the object; and a boundary detection unit for detecting a boundary between plural different tissues within the object based on the interrelationship to thereby generate information on a tissue boundary.
