断装置。 The echo signals detected by the ultrasound probe are converted into digital image signals and stored in a memory, the digital image signals stored in the memory are sequentially read out and converted into analog image signals, and the analog image signals are passed through a low-pass filter. In the ultrasonic diagnostic apparatus, the cutoff frequency of the low-pass filter is configured to be arbitrarily externally controllable without being linked to switching of the frequency of the digital image signal. An ultrasonic diagnostic device characterized by being provided with:
