ABSTRACT:
A display processor for an ultrasonic imaging system includes a two-dimensional filter to generate a smoothed image signal I.sub.p from a high spatial resolution image signal I.sub.D. I.sub.p is optimized for high contrast resolution and good tissue differentiation, and I.sub.D is optimized for high detail resolution and the display of fine structural details. I.sub.p and I.sub.D are applied as addressing inputs to a look-up table that provides an output image signal I.sub.O that combines both detail resolution of I.sub.D and contrast resolution of I.sub.p. I.sub.O can display detail resolution as brightness and contrast resolution as color. I.sub.O can also be formed as a weighted combination or sum of I.sub.p and I.sub.D.
