Ultrasound machines are undergoing intense research and rapid development in the world of medical imaging. Ultrasound machines with different technical specifications produce different qualities of ultrasound images. As the analysis and interpretation of ultrasound machines depend on the expertise of sonographers and physicians, human errors and mistakes may occur. The objective of this research is...
Ultrasound is a well-known medical imaging modality on its ability to visualize kidney, liver and pancreas accurately. However, speckle noise, caused by constructive and destructive interferences of the wavelets will disturb the image of the organs. The main goal of this paper is to identify the most suitable and reasonable filtering technique for each organ. 50 ultrasound images for each organ- kidney,...
