Abstract :
We present a basic design and experimental results of a speckle noise reduction method for ultrasound images. Our method utilizes a Wiener filtering algorithm with pseudo-inverse technique. The method is capable of solving the speckle noise problem in ultrasound image by setup a noise function of constant dB. The key idea of the Wiener filtering algorithm is to process the given ultrasound signal by making the filtering less sensitive to slight changes in input conditions. In this paper we investigate the possibility of employing this approach for pre-processing ultrasound image application. We also compare the processed images with the original one. The application of the proposed method for reducing speckle noise is demonstrated by the example.
