Speckle Noise Reduction in Medical Ultrasound Images

Speckle Noise Reduction in Medical Ultrasound Images

Ultrasound imaging is an incontestable vital tool for diagnosis, it provides in non-invasive manner the internal structure of the body to detect eventually diseases or abnormalities tissues. Unfortunately, the presence of speckle noise in these images affects edges and fine details which limit the contrast resolution and make diagnostic more difficult. In this paper, we propose a denoising appr...

Comparative Approach for Speckle Reduction in Medical Ultrasound Images

Medical images are often deteriorated by noise due to various sources of interferences and other phenomena that affect the measurement processes in an imaging and acquisition system. Speckle noise is a random mottling of the image with bright and dark spots, which obscures fine details and degrades the detectability of low-contrast lesions. Speckle noise occurrence is often undesirable, since i...

A Speckle Suppression Method for Medical Ultrasound Images Based on Local Statistics

White Matter Damage (leukomalacia) is detected by the visual inspection of ultrasound images of the neonatal brain by an expert. A need for a (semi) computerised way of segmenting the infected regions, in order to make quantitative measurements as an aid to the subjective diagnosis, is felt. The performance of snakes for this purpose, however, is heavily deteriorated by the presence of speckle ...

On Speckle Noise Reduction In Medical Ultrasound Images

In general, one of the main problems to be solved in the processing of biomedical images is the noise reduction. The problem is particularly important if the noise has a multiplicative nature (speckle). We present a review of techniques that can be used to reduce this kind of noise in ultrasound images. That techniques have been used on B-mode echocardiograms with four-chamber view, selecting a...
