Creators

Description

This patent describes an ultrasound imaging system adapted to receive temporally related image frames, each frame comprised of signals representative of reflected ultrasonic waves derived from scanning of an image plane in a patient. The system includes a gain controlled amplifier and image formation means adapted to produce at least one image based upon the image frames and responsive to signals from the gain controlled amplifier. A gain control system discriminates between signals from non-attenuating fluid filled regions and signals from attenuating reflective tissue regions comprising
