Survey of Despeckling Techniques for Medical Ultrasound Images

Ultrasound imaging is the most commonly used imaging system in medical field. Main problem related to this imaging technique is introduction of speckle noise, thus making the image unclear. The success of ultrasonic examination depends on the image quality which is usually retarded due to speckle noise. There have been several techniques for effective suppression of speckle noise present in ultrasound images. This paper presents a review of some significant work carried out for despeckling of ultrasound images.
