Variable compression of ultrasonic image data with depth and lateral scan dimensions |
摘要 |
<p>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 is varied with both the range (depth) and lateral (scanline to scanline) dimensions of an ultrasonic image. <IMAGE></p> |
