Image processing system and method of enhancing the quality of an ultrasound image

Abstract

The present invention relates to an image processing system for enhancing the image quality of an ultrasound image. The image processing system may include: an image data forming unit for forming image data based on image signals acquired from a target object; a log-compression unit for log-compressing the image data to provide a log-compressed image; a TGC processor for analyzing a vertical profile of pixel intensities in the log-compressed image and automatically setting a TGC (time gain compensation) parameter based on the analysis result; a gain processor for calculating mean brightness of pixels included in the log-compressed image applying the set TGC parameter and comparing the calculated mean brightness with predetermined brightness, thereby automatically setting a gain parameter based on a comparison result; a DR processor for automatically setting a DR (dynamic range) parameter by using edge contrast and background roughness of the log-compressed image applying the set TGC and gain parameters; and an image forming unit for applying the TGC, gain and DR parameters to the image data.
