Abstract
Introduction Medical Ultrasound (US) Imaging technique is a non-ionizing radiations imaging modality that enables real time diagnosis treatment. This technique has non-invasive nature. It is widely used in medical field for diagnosis, patient routine check-ups for good health, and more and more u

Medical Ultrasound (US) Imaging technique is a non-ionizing radiations imaging modality that enables real time diagnosis treatment
We focused on minimization of speckle noise effect in US images
Speckle noise effect is spatially correlated with correlation length which is calculated by the autocorrelation of the point spread function (PSF)
Summary
Medical Ultrasound (US) Imaging technique is a non-ionizing radiations imaging modality that enables real time diagnosis treatment. Perona and Malik filter[7] is firstly adopted the anisotropic diffusion technique for speckle noise reduction in US Images. This filter avoids the unnecessary smoothing related with linear diffusion techniques, but not preserve edges details. The Lee filter reduces the speckle noise by applying a spatial filter to each pixel in an image, which filters the data based on local statistics calculated within a square window. ADMBSS filter[8] is to eliminate the effect of gradient information due to the lack of contours and low contrast of US images with objective of preservation of relevant clinical details in interest region using probabilistic-driven selective memory mechanism filtering This filter is adapted to the US medical imaging context[9]. Preserving pathway of the time dependent probability for getting more robust characterization than obtained from instantaneous probability,
