Systems and methods for improving the quality of ultrasound images made up of a combination of multiple sub images include giving more weight to sub image information that is more likely to improve a combined image quality. Weighting factor information may be determined from the geometry (e.g. angle or path length) of a location of one or more specific transducer elements relative to a specific point within a region of interest or a region of an image. In some embodiments any given pixel (or other discrete region of an image) may be formed by combining received echo data in a manner that gives more weight to data that is likely to improve image quality and/or discounting or ignoring data that is likely to detract from image quality (e.g. by introducing noise or by increasing point spread).
