Abstract: The enhancement of pseudo-color in B-Scan ultrasonic images is significant to medical diagnostics. A new method is presented to re-divide the function fields transferred in segments during the gray-color transformation. In this method, the values of gray image are first clustered based on the improved K-means Algorithm. Then the nodes of segment transfer function are reset according to the value of each grey cluster. By comparing the experiment results, it can be seen that the images processed using this method is much clearer and more gradational and the focus part can be displayed effectively for medical diagnostics.
