Ultrasound imaging is the most generally used in medical diagnosis and it is corrupted by
speckle noise, which is multiplicative. For a better diagnosis, there is also a need to …

Ultrasound plane wave (PW) imaging is a cutting-edge technique that enables high frame-
rate imaging. However, one challenge associated with high frame-rate ultrasound imaging is …

In this study a novel approach based on 2D FIR filters is presented for denoising digital
images. In this approach the filter coefficients of 2D FIR filters were optimized using the …

Congenital heart defects (CHD) are one of the serious problems that arise during
pregnancy. Early CHD detection reduces death rates and morbidity but is hampered by the …

Ultrasound imaging is one of the most popular noninvasive techniques for diagnosis than
other imaging modalities like X-rays, MRI, and CT scans because of ultrasonic techniques …

Speckle noise of ultrasound images is of multiplicative nature which degrades the image
quality in terms of resolution and contrast. While there exist a number of algorithms for …

This paper extends the results on reverberation identification and removal in ultrasound
imaging to present an mathematical model for iterative representation of the echo time …

Nowadays medical imaging plays an important role in the detection of defects before
proceeding with any medical procedures. During pregnancy, medical imaging plays a major …

In this paper, we describe a speckle noise reduction method for ultrasound images based on
the undecimated wavelet packet transform (UWPT). Recent wavelet domain despeckling …

This paper presents a new super-resolution (SR) technique that is applied to the imaging
systems (eg ultrasound sector scanner) where image data are acquired in polar format …
