Time gain compensation implementation
First Claim
Patent Images
1. A time gain compensation apparatus for use with ultrasound imaging systems comprising:
- a TGC curve generator;
a means for driving the TGC curve generator to generate a base curve, the base curve defined by an initial gain and data represented by a series of slopes and associated time-dependent break-points, the TGC curve generator further having an associated vector number gain offset for providing an offset value to be added to the base curve, to provide digital generation of the time gain compensation curve.

Abstract
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.
