This paper presents a novel adaptation of the median filter to the problem of boundary-
preserving speckle reduction in ultrasonic imaging. The technique involves applying a bank …

Breast ultrasound (BUS) is considered the most important adjunct method to mammography
for diagnosing cancer. However, this image modality suffers from an intrinsic artifact called …

In the field of biomedical imaging, the ultrasound (US) B-Scan images are used for tissue
characterization. These images are obtained with a simple linear or sector scan US probe …

Using a good statistical model of speckle formation is important in designing an adaptive
filter for speckle reduction in ultrasound B-scan images. Most clinical ultrasound imaging …

A high-sample rate 3D median filtering processor architecture is proposed, based on a novel
3D median filtering algorithm, that can reduce the computing complexity in comparison with …

A 3D median filter architecture suitable for FPGA implementation is presented. The
architecture consists of an ordered semi-systolic array of size equal to the filter window size …

Ultrasound imaging is widely used in medical areas. By transmitting ultrasound signals into
the human body, their echoed signals can be rendered to represent the shape of internal …

This paper extends speckle filtering from two to three dimensions to exploit the temporal
nature of speckle to improve its reduction. A motion adaptive two-dimensional least mean …
