PURPOSE:To obtain the ultrasonic diagnostic device which can stop recording of an ultrasonic image to an auxiliary recorder in the beginning and the end periods of a linear scanning, inputs automatically only a cross section image of an equal interval, and can execute exactly a three-dimensional image processing. CONSTITUTION:The ultrasonic diagnostic device is provided with a control circuit 22 for controlling a rotation and a movement of an ultrasonic vibrator, a CD power source 19 for supplying power to a DC motor 8 for rotating the ultrasonic vibrator, and a DC motor control circuit 20 for controlling a voltage of the DC power source 19. As for the control circuit 22, position detecting signals K, L of a photo-interrupter 16 are inputted in advance, and the circuit controls a rotation of a stepping motor 13 for moving forward and backward the ultrasonic vibrator. To a recording controller 24, an auxiliary storage device 25 is connected. By synchronizing with a synchronizing signal M which is not outputted in the beginning and the end periods of a linear scanning from the control circuit 22, a write command can be transmitted. |
