Wave shaping of ultrasonic echoes using inverse dynamic filter

Abstract

An inverse dynamic filter is applied to enhance the quality of the ultrasonic B-scan image. The designed filter is inserted in the ultrasonic B-scan sector system in order to observe the effect of an inverse dynamic filter. The filtered image has the better resolution than the unfiltered image. Using a B-scan image of a tissue-equivalent phantom, we demonstrate the application of the inverse dynamic filter to improve medical ultrasonic images.
