Abstract
A gain control system for use in an ultrasound imaging system includes a histogram analyzer for identifying image pixel populations attributable to fluid, soft tissue, specular reflectors and artifacts. The histogram analyzer establishes mean peak values. Nulls between image populations are identified for setting gain versus depth break points. A comparator uses a threshold level to compare image information corresponding to soft tissue. A TGC generator responds to a preselected slope, a brightness level, and the tissue identification to generate a time gain control signal.
