1. An ultrasonic diagnosis apparatus which performs a scan of an interior of a subject to obtain two-dimensional image data of the interior, detects a position and an orientation of a scanning plane of the scan according to which the two-dimensional image data is obtained, and creates and outputs a two-dimensional ultrasound image of the interior based on the position and the orientation detected and the two-dimensional image data, the ultrasonic diagnosis apparatus comprising: an image processing controlling unit that creates a guide image which corresponds to an anatomical position and orientation of the two-dimensional ultrasound image based on anatomical image data which is previously stored as anatomical image data of a human body; and a display unit that outputs and displays various types of images including the guide image and the two-dimensional ultrasound image so that plural images are simultaneously output and displayed.
