PURPOSE:To always display a concern region in a stationary state, by providing an apparatus for measuring the moving speed of a reflecting body and a control part changing a display position corresponding to the moving speed. CONSTITUTION:A wave transmitting part 2 is used to receive the reflected signal of an object by an array type ultrasonic probe 1. The receiving signal obtained by a phasing device 3 is formed into an image according to a usual B-mode ultrasonic image regeneration method by a processing part 4 to be displayed on a display part 5. Herein, the moving speed relating to the signal from the interior of the art 7 indicated by an ROI setting part 6 of a concern region is measured by a moving speed measuring part 8. This measured value 9 is used to control the operation of the processing part 4 and the position of the display part 7 is moved in the same direction as the movement of matter. By this method, the image of the matter displayed on an ROI display part 10 is not affected by the motion of the object and the matter is displayed in a stationary state even when the magnification of the ROI part is increased. |
