An ultrasonic diagnostic apparatus including a line-of-sight position data obtaining unit that obtains current line-of-sight position data of the operator from a line-of-sight position input unit, and a setting condition change unit that changes an area that is set based on the line-of-sight position data. Further, the setting condition change unit refers to focal point position setting condition database and changes a focal point position that is set based on the set area data. A control unit shifts the focal point position to a transmission unit and a reception unit. Furthermore, the setting condition change unit refers to the image quality setting condition database and changes a set image quality setting condition to an optimal image quality setting condition based on the set area data.
