Abstract:

An ultrasound imaging system lateral gain control circuit operates in conjunction with an ultrasound imaging system for generating an ultrasound image of an ultrasound analysis object using an ultrasound sensing circuit for sensing an ultrasound signal returning from an ultrasound analysis object to an ultrasound transducer. The ultrasound image is defined by a first region and a second region. The first region and second region together form the complete ultrasound image. The first region associates with a region proximate to the ultrasound transducer, while the second region associates with a region distal from the ultrasound transducer. The lateral gain control circuit controls the two-dimensional ultrasound image brightness between the two regions by controlling the ultrasound signal amplification by separately controlling the first region signal amplification and the second region signal amplification.
