Image processing to reduce ultrasonic speckle.
The most significant source of noise in contemporary ultrasonic images is ultrasonic speckle, a phenomenon relating to random interference of ultrasonic waveforms in transducer sample volumes. Averaging of a number of ultrasonic images, which are slightly spatially shifted with respect to one another, leads to image improvement via speckle reduction. Such processing may provide a useful improvement of clinical ultrasonic images.
