When a tomographic image is displayed, the operator of an ultrasonic diagnostic apparatus is allowed to know the timing to optimize the image quality and decide by him- or herself whether optimization needs to be done now or not. The ultrasonic diagnostic apparatus includes: an ultrasonic probe for sending out an ultrasonic wave toward a vital tissue and receiving a reflected wave of the ultrasonic wave reflected from the tissue; an image constructing section for constructing an image frame representing a tomographic image of the tissue by calculating the magnitudes of displacements at multiple measuring sites on the tissue based on the reflected wave; a display section for displaying the image frame thereon; and a processing section for analyzing an image feature quantity of the image frame and comparing the image feature quantity to a predetermined reference feature quantity. Based on a result of the comparison, the apparatus gives a notification that it is time to decide whether its operator wants the image quality of the image frame to be optimized now or not.

Ultrasonographic device

An ultrasonic diagnostic apparatus including a transmitter section for driving a probe so that a subject is scanned with an ultrasonic beam over a predetermined period of time; a receiver section for receiving, using the probe, an echo resulting from the ultrasonic beam being reflected by the subject, and producing a receive signal for each passage of the predetermined period of time; an image constructing section for producing a tomographic image frame composed of brightness information based on an intensity of the receive signal for each passage of the predetermined period of time, and adjusting brightness of the produced tomographic image frame with a set gain; a gain control section for producing the set gain; and a display section for displaying the tomographic image frame whose brightness has been adjusted.
