Under the alternating electrical excitation, biological tissues produce a complex electrical
impedance which depends on tissue composition, structures, health status, and applied …

Medical imaging methods, such as CT scans, MRI scans, X-rays, and ultrasound imaging,
are widely used for diagnosis in the healthcare domain. However, these methods are often …

In recent years, variant networks derived from U-Net networks have achieved better results
in the field of medical image segmentation. However, we found during our experiments that …

Ultrasound medical images are very important component of the diagnostics process. They
are widely used since ultrasound is a non-invasive and non-ionizing diagnostics method. As …

Image denoising performs a prominent role in medical image analysis. In many cases, it can
drastically accelerate the diagnostic process by enhancing the perceptual quality of noisy …

Speckle noise is an inherent yet ineffectual residual artifact in medical ultrasound images,
which significantly degrades quality and restricts accuracy in automatic diagnostic …

Background and objective Medical images are contaminated by multiplicative speckle noise
which significantly reduce the contrast of ultrasound images and creates a negative effect on …

The operations of digitization, transmission and storage of medical data, particularly images,
require increasingly effective encoding methods not only in terms of compression ratio and …

This paper presents a novel parametric thresholding procedure to reduce the effect of
speckle noise in ultrasound (US) medical images. The method comprises the use of an …

Ultrasonography is highly used as an image tool for medical diagnosis due to its non-
invasive nature, low cost, adaptability and the possibility of real-time visualization. However …
