PROBLEM TO BE SOLVED: To eliminate distortion of a rendering image by correcting distortion of a tomographic surface of a reflection echo due to scanning while mechanically moving an ultrasonic probe.SOLUTION: In this ultrasonic diagnostic apparatus, while the ultrasonic probe including a plurality of vibrator elements arrayed in the direction of a major axis is mechanically moved in the vertical direction to the direction of the major axis, data for two or more frames is acquired, and a tomographic image or a 3D image is created from the frame data. Concerning each of vibrator elements, scan data (A) of a current frame and scan data (B) of a frame ahead are acquired, a distance (LA) between a reference position X point vertical to the moving direction of the ultrasonic probe and the scan position A point of the current frame and a distance (LB) between the reference position X point and the scan position B point of one frame ahead are obtained, and data at the reference position X point is obtained by interpolation, thereby correcting the receiving position of the frame data caused by the mechanical movement of the ultrasonic probe. |
