Speckle Detection in Ultrasound Images Using First Order Statistics
It is necessary to identify speckled regions in ultrasound images to control adaptive speckle suppression algorithms, for tissue characterisation, and to estimate the elevational separation of B-scans by speckle decorrelation. Previous authors have proposed classification techniques based on second order powers of the homodyned k-distribution, or lower order powers of the more limited k-distrib...
متن کاملSpeckle Detection in Echocardiographic Images
B-scan Echocardiographic images unlikely carry unlikely images by scattering of ultrasound beams backed from structures within the body organ that is being scanned. Two major types of scatterings are diffused and coherent scatterings. Diffuse scatterings are caused when there are a large number of scatterers is with random phase within the resolution cell of the ultrasound beam and causes speck...
متن کاملParameter Estimation of the Homodyned K Distribution Based on Signal to Noise Ratio
The Homodyned K (H-K) distribution is very important in Ultrasound (US) imaging because it models the speckle in a general way, even if the number of scatterers per resolution cell is low and if a coherent component exists. Due to the analytical complexity of this distribution, only a few works based on the H-K have been reported and other simpler distributions have been used instead. Here we p...
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 کاملEstimation Method of the Homodyned K-Distribution Based on the Mean Intensity and Two Log-Moments
The homodyned K-distribution appears naturally in the context of random walks and provides a useful model for the distribution of the received intensity in a wide range of non-Gaussian scattering configurations, including medical ultrasonics. An estimation method for the homodyned K-distribution based on the first moment of the intensity and two log-moments (XU method), namely the X and U-stati...
