dc.description.abstract Ultrasound imaging is a widely used medical tool that can help physician evaluate ,diagnose and treat medical conditions and, due to its noninvasive nature, low cost and capability of forming real time imaging it is widely used technique and considered very safe due to non ionizing radiation properties unlike X-ray .the ultrasound image shows granular appearance called speckle ,this noise decrease the human ability to identify pathological from normal tissue because it depends on the structure of the image tissue and various imaging parameters. The main purpose for speckle reduction in medical ultrasound imaging to improve the human into keep in mind that certain speckle contains diagnostic information and should be retained. The objective of this thesis is to give an overview about types of speckle reduction techniques in ultrasound imaging and to present tow new techniques of speckle reduction. And to carry out comparative evaluation of despeckle filtering based on image quality evaluation metrics. A new speckle suppression methods and coherence enhancement of medical ultrasound images where proposed: The first one is modified of hybrid median filter, the second one is combining of SRAD with hybrid median filter. It has been found that quality evaluation metrics the proposed methods performed better than all other methods while the structural details and results preserved edges and features in a better way than other despeckling filters en_US
