置。[Claim for Utility Model Registration] Echo signals from an ultrasound probe are written into an image memory, and the echo signals from this image memory are sequentially transmitted.
In an ultrasonic diagnostic apparatus equipped with a window processing function that reads and emphasizes the echo signal level in a specific range and displays it on a display, the echo signal level of the original image within the specific range is determined based on the echo signal from the image memory. A histogram creation circuit that creates a histogram of a distribution, and an echo level/gray level conversion curve (γ
and a conversion circuit that converts the echo signal level from the image memory to a gray level suitable for image display based on the conversion curve from the quantization circuit and outputs the gray level. An ultrasonic diagnostic device featuring:
