Computerized anisotropic diffusion of two dimensional ultrasonic images using multi-direction spreading approaches

Abstract

Ultrasound medical imaging is widely used nowadays in clinical application due to its intuitive,convenient, safety, non-invasive, and low cost. However, ultrasound image formation always comes withspeckle-noise which will greatly reduce the image quality, and makes the identification and analysis of imagedetail become more challenging. Hence, we present an extended robust diffusion algorithm for optimumdiffusion while retain the edge of image features. Total eight spreading diffusion directions are implemented inthe proposed algorithm. Finding showed that this method is able to provide consistent and more objectiveresults.
