An ultrasonic diagnostic apparatus is provided with a boundary extraction unit (2) that extracts boundaries between media appearing in an ultrasonic image based on the intensity of each of received signals. A boundary extraction unit performs boundary extraction processing on each of individual time series ultrasonic images sequentially generated while operating an ultrasonic probe to move, sets a target region (margin region) matched to a movement operation of the ultrasonic probe in an ultrasonic image being processed from a boundary extracted in an ultrasonic image preceding the ultrasonic image being processed, and performs processing of extracting a boundary in the ultrasonic image being processed by using received signals corresponding to the reflection waves reflected at an inner side of the target region thus set. |
