摘要: An inherent property of medical ultrasound imaging is the speckle noise that generally obscures image and reduces diagnostic resolution contrast. Consequently, substantial improvement images an important prerequisite for imaging. Some recent research has suggested spatial distribution tissue densities may be used in to reconstruct with fewer speckles. This new approach based on direct estimation density from radio frequency echo signals received by probe. paper presents a mathematical analysis this derives simplified model issue estimation. simplifies computation involved provides deeper insight into problem. It shows reconstruction have limited effect embedded RF signal. The results are verified numerical calculations simulation examples.
