A New Medical Feature Enhancing Speckle Suppression Method for Ultrasound Images of the Neonatal Brain

چکیده
In this paper we introduce a new smoothing technique based on a noise model for the speckle noise as represented in the image. Using this model and measurements reported earlier in literature we are able to distinguish speckle noise from important resolvable details. All individual speckles are located, and exploiting our knowledge on the speckle classification, the filter removes the noise speckles, while it preserves valuable details. We show that applying the proposed technique yields a significant speckle suppression in the image, while valuable image data are preserved. Keywords—speckle; medical ultrasound; filtering; neonatal brain

Segmenting “Flares” in Ultrasound Images Using Prior Statistics
The common method neonatologists use nowadays to determine White Matter Damage (leukomalacia) is by visual inspection of ultrasound images of the neonatal brain. A need for a (semi)computerized way of delineating the affected regions, in order to make quantitative measurements as an aid to the subjective diagnosis, is felt. The use of active contours for this purpose is a classical approach [1,...
متن کاملTemperature Mapping Using Ultrasound Digital Images
Introduction: The success of hyperthermia depends on the accuracy of the temperature monitoring in the tumor and the surrounding normal tissue. In this study, the temperature changes were determined by computing the speckle displacement in the ultrasound digital images. Speckle tracking algorithm was used to compute the displacement. Materials and Methods: The experiment was perf...
متن کاملA 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 ...

Noise Suppression and Motion Estimation in Medical Ultrasound Imaging by Yong Yue Echocardiographic imaging is a primary modality in the diagnosis of heart disease. Compared to other imaging techniques, such as X-Ray, MRI, and PET, ultrasound imaging owes its great popularity to the fact that it is a safe and non-invasive procedure for visualizing the heart and vasculature. The ultrasound image...
