PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus capable of displaying a composite image in which display transmittance of a reference image with respect to a contrast image is changed.SOLUTION: The ultrasonic diagnostic apparatus includes a composite image display control section 62 which causes a composite image to be displayed, the composite image being obtained by compositing the reference image and the contrast image in a predetermined composite ratio, and which changes the composite ratio with the passage of time. The composite image display control section 62 reduces the composite ratio of the reference image with the passage of time. The ultrasonic diagnostic apparatus further includes a time counting section which starts counting the time in predetermined timing, and the composite image display control section 62 changes the composite ratio each time when a predetermined time elapses from the start of time counting by the time counting section. |
