PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus facilitating an operation performed by an operator for displaying information on an optimum blood flow rate.SOLUTION: An ultrasonic diagnostic apparatus includes an ultrasonic probe 1, an acquisition part 161 and a control part 18. The ultrasonic probe performs ultrasonic scanning to a subject to receive reflection waves from the subject. The acquisition part acquires a correspondence relation specifying a position of a correspondence cross section corresponding to a scanning cross section of the ultrasonic probe, in volume data where the subject is imaged by any other medical image diagnostic apparatus. The control part displays a position marker showing a collection range of blood flow information in the scanning cross section at a corresponding position on the cross-sectional image of at least the correspondence cross section, on the basis of the correspondence relation.SELECTED DRAWING: Figure 1
