1. A method for implementing a speckle reduction filter comprising:
- receiving a processed data stream from a processor;
dividing the processed data stream into data subsets;
simultaneously filtering the data subsets by using a speckle reduction filter to produce filtered data subsets; and
producing an image data stream based on the filtered data subsets.

Abstract
A method for implementing a speckle reduction filter are described. The method includes receiving a processed data stream from a processor, dividing the processed data stream into data subsets, simultaneously filtering the data subsets by using a speckle reduction filter to produce filtered data subsets, and producing an image data stream based on the filtered data subsets.

14. A method for implementing a speckle reduction filter comprising:
-
receiving beams from a beamformer;
frequency compounding the beams to obtain a filtered image data stream;
receiving a processed data stream from a processor;
dividing the processed data stream into data subsets;
simultaneously filtering the data subsets by using a speckle reduction filter to produce filtered data subsets;
producing a second image data stream based on the filtered data subsets; and
simultaneously co-displaying a filtered image and a second image on a common screen, wherein the filtered image is generated from the filtered image data stream and the second image is generated from the second image data stream.
