Abstract
The present invention is an ultrasound imaging system that displays images with improved dynamic range. An echo signal is sampled so that each sample contains at least N bits in order to create a digital echo signal having at least 2.sup.N possible values that determine a dynamic range of the digital echo signal. A single-color lookup table is generated having approximately 2.sup.N RGB component entries, each entry defining a pixel having a unique hue, intensity, and saturation value. Each sample of the digital echo signal is mapped to an RGB component entry of the single-color lookup table, and the mapped RGB components are displayed on the display to produce a single-color image having a dynamic range that is substantially equal to the dynamic range of the digital echo signal.
