PURPOSE:To improve the real-time property by increasing the number of frames in an ultrasonic diagnostic device. CONSTITUTION:In an ultrasonic diagnostic device in which ultrasonic waves are transmitted and received plural times in the same direction to obtain one ultrasonic raster, and B-mode image information and blood image information are determined on the basis of the obtained receiving signal and displayed, the blood image information is compared with a determined value every ultrasonic raster displayed on a screen, whereby the presence of a blood signal is detected, and on the basis of the detection result, the frequency of transmission and receipt in the same direction of ultrasonic waves to obtain one ultrasonic raster is reduced in the area in which the blood signal is absent. |
