Abstract

This paper describes the image formation in medical ultrasound for the case of scattering media. The texture statistics are dominated by speckle formation. The effects of spatial, fixed and adaptive, filtering, as well as, of grey scale encoding on the detection of lesions are analytically described and illustrated with representative images.
