The ultrasonic imaging apparatus comprises an ultrasonic probe, a detecting part, a position analyzing part, a display control part, a display part, and a storage part. The detecting part is mounted on the ultrasonic probe operable to detect a part of a prescribed pattern formed on an ultrasonic low attenuation medium. In the storage part, the prescribed pattern formed on the ultrasonic low attenuation medium has been preliminarily stored. Upon receipt of detection results from the detecting part, the position analyzing part specifies the position of a part of the detected pattern on the prescribed pattern by referring to the prescribed pattern stored in the storage part. The display control part controls the display part to display the positional relation between the ultrasonic probe and the subject to be examined regarding the position of a part of the prescribed pattern that has been detected as the position of the ultrasonic probe.
