The electrical signals may be input to the control unit as imaging signals and then may be displayed on the first section of the display unit as a diagnostic imaging (S1120).
The diagnostic imaging and a reference image may be synchronized (S1130), and during the synchronization, the diagnostic imaging may be compared with at least one reference images stored in the storage unit, and then the most similar reference image to the diagnostic imaging, which is identical to the diagnostic imaging, may be selected. In this case, the selection of the reference image may be performed by estimating by ultrasound imaging apparatuses, or by selecting a single reference image through the input unit by displaying at least one reference images on the display unit.
A reference image may be a reference for a target part of an object and a diagnostic position, and the user may guess where are the target part and the diagnostic position on the basis of the reference image.

Accordingly, the image indicator may be moved (S1160). In this case, the position and the location of the ultrasound probe may be determined based on a detected signal by the detecting unit provided in the ultrasound probe and may be determined based on the changed diagnostic imaging of the object. Particularly, when the position and the location of the ultrasound probe are detected by an angular velocity sensor, a magnetic sensor, an acceleration sensor, a gravity sensor, and a gyro sensor, all of which are provided in the ultrasound probe, the image indicator may be changed from the reference position and the relative location to a relative position and a relative location. In addition, as mentioned above, the reference image, which is the most similar to the changed diagnostic imaging, may be selected, and the ultrasound imaging apparatus may estimate the relative position and the relative location based on the relation between reference information about the reference image of the changed diagnostic imaging and a preset reference position and location, and accordingly the image indicator may be moved.
