Abstract
Perception of complex structures independent from viewing angle and distance demonstrates the superiority of the human eye compared to every computed system. Thus qualitative image improvement can only try to improve information presentation of images offered to the retinal receptor-cortex system. In ultrasound images obtained from the subcostal view of the liver the parenchyma consists of a range of 80–100 gray levels. The human eye being capable of differentiating up to 35 gray levels in moving images1 looses offered information content to a great extend.
