ULTRASONIC IMAGE DIAGNOSTIC APPARATUS, AND ULTRASONIC IMAGE DIAGNOSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic image diagnostic apparatus and an ultrasonic image diagnosis method capable of clearly extracting an anisotropic region.SOLUTION: A transmit part 12 and a receive part 13 drive a plurality of transducers 2a to repeatedly transmit and receive ultrasonic waves in two or more different directions, so that scanning of ultrasonic waves is performed two or more times to overlap a part or the whole of a scan area. An image processing part 15 generates a plurality of component image data from a receive signal obtained as a result of scanning with ultrasonic waves by the transmit part 12 and the receive part 13. An anisotropic region detecting part 16 evaluates anisotropy of reflection of the ultrasonic waves in a subject on the basis of at least one of ultrasonic image data and the receive signal. The image processing part 15 generates composite image data obtained by composing the plurality of component image data according to an evaluation result of the anisotropic region detecting part 16.
