Abstract: A system for visualization and quantification of ultrasound imaging data may include a display unit, and a processor communicatively coupled to the display unit and to an ultrasound imaging apparatus for generating an image from ultrasound data representative of a bodily structure and fluid flowing within the bodily structure. The processor may be configured to generate vector field data corresponding to the fluid flow, wherein the vector field data comprises axial and lateral velocity components of the fluid, extract spatiotemporal information from the vector field data at one or more user-selected points within the image, and cause the display unit to concurrently display the spatiotemporal information at the one or more user-selected points with the image including a graphical representation of the vector field data overlaid on the image, wherein the spatiotemporal information includes at least one of a magnitude and an angle of the fluid flow.

Abstract: The invention provides an ultrasound data processing method for pre-processing signal data in advance of generating ultrasound images. The method seeks to reduce noise through application of coherent persistence to a series of raw ultrasound signal representations representative of the same path or section through a body but at different successive times. A motion compensation procedure including amplitude peak registration and phase alignment is applied to raw echo signal data in advance of application of persistence in order to cohere the signals and thereby limit the introduction of motion induced artifacts.

Abstract: An apparatus can be used to generate acoustic imaging pulse sequences and receive corresponding echoes elicited by the acoustic imaging pulse sequences. An acoustic radiation force (ARF) pulse sequence can be generated to agitate a contrast medium in a tissue region between the acoustic imaging pulse sequences. A decorrelation between images corresponding to the received echoes can be determined. A weighting map can be applied to an image to weight a region of the image corresponding to a spatial location of the contrast medium using the determined decorrelation. In an example, the receiving of corresponding echoes elicited by the acoustic imaging pulse sequences can include receiving acoustic energy having a range of frequencies offset from a fundamental frequency associated with the acoustic imaging pulse sequences. An acoustic imaging pulse sequence can include a pulse having an inverted amplitude envelope with respect to another pulse included in the sequence.
