Ultrasonic diagnosis apparatus

An ultrasonic diagnosis apparatus comprising:

• an ultrasonic image generation section that generates an ultrasonic image based on a reception signal from an ultrasonic probe that transmits an ultrasonic wave to a subject and receives the ultrasonic wave from the subject;
• a position information acquisition section that includes a position sensor mounted to the ultrasonic probe and acquires position information on a three-dimensional space of the ultrasonic probe;
• an image acquisition section that obtains image data and acquires a reference image corresponding to the ultrasonic image;
• a reference image forming section that identifies a to-be-displayed cross section orientation of acquired the reference image according to at least one of information related to an examination purpose for the subject and information related to a type of the ultrasonic probe, and forms a reference image which a cross section orientation is identified;
• and
• a display section that displays a formed reference image by the reference image forming section and ultrasonic image formed by the ultrasonic image generation section.
