Traditional spatial compounding, in general, employs multiple distinct transmit/receive beam angles which insonify a common region, from which multiple images are formed. The individual images are detected, resampled onto a common grid, and combined

A constant sound speed of 1.54 mm/micros is generally used by ultrasound imaging systems for delay and timing. However, the body's sound speed in-homogeneity can lead to defocusing and increased clutter. To provide an improvement using standard trans

A contrast quantification package has been developed to be part of a medical ultrasound system. This package provides motion compensation through nonaffine image registration. An explanation of the image registration system is given. A set of analyse

Methods and systems are provided for automatic optimization for ultrasound medical imaging. In one approach, velocity values are unwrapped to avoid aliasing artifacts. Multi-dimensional phase unwrapping is applied to the velocity data. The unwrapped

An ultrasound image is morphed for perfusion assessment. Various images within a sequence of images or movie clip are mapped to one frame of reference using local warping. Nonlinear local image transformations or other warping based on local estimate
