Abstract
A method and an apparatus for automating time-gain compensation (TGC) and lateral-gain compensation (LGC) based on the B-mode image data. The automatic gain adjustments are aimed at equalizing the mean signal intensities along the axial (for TGC) and/or lateral (for LGC) direction of the image, and suppressing any lateral band (for TGC) and/or sector (for LGC) that contains mostly noise. The automatic TGC/LGC adjustment method is implemented in software on a digital scanner and uses a noise model of the entire B-mode processing chain from the beamformer through the B-mode processor to the back-end video processor.
