ABSTRACT:
The present invention comprises an image processing system to process an array of ultrasonic scanning image data. The image processing system is capable of performing local attenuation estimations by the use of the scanned data and displaying the estimated local attenuations in clearly identifiable images whereby the results of the ultrasonic scan can be accurately and easily interpreted. The estimation process comprises the steps of macro segmentation, micro segmentation, classification, and filtering wherein various techniques of average thresholds, classification and homogenization are used to minimize measurement noises and determine the pixels within a homogeneous geometrical element.
