Paper Abstract

Ultrasound images of moving anatomic structures such as the human heart and other organs are distorted by noise, which may destroy important information. Because of the noise, the contours in the picture are difficult to recognize. Previously, various algorithms like `symmetrical exponential filtration' have been described as good noise-reducing tools. In this work, we used a modified median filtration carried out on triplets of frames from the video signal.
