Improved ultrasound imaging of vasculature

The current invention concerns a method, a computer system, and a computer program product for blood vessel image extraction from ultrasound signals, and a method and apparatus for ultrasound imaging. A set of ultrasound signals at successive times in a plurality of spatial points is obtained. The ultrasound signals are decomposed as a sum of terms. Each term consists of a time-independent spatial component image factor and a space-independent temporal component signal. The spatial component images are mutually orthonormal. The temporal component signals are mutually orthogonal. A sharpened spatial image for each of multiple spatial component images is determined. A processed image being a bilinear combination of multiple sharpened spatial images is generated.
