Abstract
An ultrasonic diagnostic imaging system processes echo information signals by means of a dynamic range map for displayed signals which is varied automatically throughout the image to control the displayed dynamic range and noise rejection level in regions of the image. In a preferred embodiment the displayed dynamic range and noise rejection level varied with both the range (depth) and lateral (scanline to scanline) dimensions of an ultrasonic image.
