WebDiffuse reverberation clutter, or diffuse clutter, has a speckle-like appearance in ultrasonic images, and may look no different than tissue. There are currently no models of diffuse clutter; however, we hypothesize that diffuse clutter originates from multi-path or multiple scattering of structures. WebA general filtering method, called the singular value filter (SVF), is presented as a framework for principal component analysis (PCA) based filter design in medical ultrasound imaging. The SVF approach operates by projecting the original data onto a new set of bases determined from PCA using singular value decomposition (SVD).
