Abstract
A method and apparatus for adaptively enhancing a scanned ultrasound image of a body portion having both areas of tissue and areas of blood pool. Clutter which appears in the blood pool areas is removed by processing the image signal to generate a mask signal, which signal is substantially present in areas of tissue to pass such areas and is substantially not present in areas of blood pool to block such areas. The image signal is modulasted with the mask signal, preferably on a pixel-by-pixel basis, to substantially remove the clutter.
