Subspace-based technique for speckle noise reduction in ultrasound images

Subspace-based technique for speckle noise reduction in ultrasound images

BACKGROUND AND PURPOSE Ultrasound imaging is a very essential technique in medical diagnosis due to its being safe, economical and non-invasive nature. Despite its popularity, the US images, however, are corrupted with speckle noise, which reduces US images qualities, hampering image interpretation and processing stage. Hence, there are many efforts made by researches to formulate various despe...

Speckle Noise Reduction in Ultrasound Images using Fuzzy Shrinking Technique

An ultrasound image provides the radiologist with noninvasive, low cost, and real-time images that can help them in diagnosis, planning and therapy. However low PSNR (picture signal to noise ratio) in ultrasound images causes difficulties in correct interpretation of ultrasound images. Further speckle noise present in ultrasound images is considered to be the major cause of its low PSNR. In thi...

Speckle Noise Reduction in Ultrasound Images

Ultrasound imaging is a widely used medical imaging modality because it is safe, allows real-time visualization of moving structures, and is relatively inexpensive. But the major issue with ultrasound images is the presence of speckle noise, which is an inherent limitation of ultrasound images. Various filters are used to reduce the speckle noise and to enhance the quality of the image. This wo...

Speckle Noise Reduction in Medical Ultrasound Images

Ultrasound imaging is an incontestable vital tool for diagnosis, it provides in non-invasive manner the internal structure of the body to detect eventually diseases or abnormalities tissues. Unfortunately, the presence of speckle noise in these images affects edges and fine details which limit the contrast resolution and make diagnostic more difficult. In this paper, we propose a denoising appr...
