Beschreibung
Zusammenfassung:	A time gain compensation technique is applicable for use with ultrasound imaging systems, including systems having digital architecture. The time gain compensation apparatus of the present invention comprises a time gain compensation curve generator and the ability to drive the time gain compensation curve generator to provide digital generation of the time gain compensation curve. Digital generation of the time gain compensation curve is achieved by an initial gain and data represented by a series of slopes and associated time-dependent break-points.
