Problems solved by technology

The disadvantage of this defocusing technique is that the spatial specificity produced by bidirectional beamforming is greatly reduced, which leads to increased sidelobe levels near strong reflectors

Abstract

The invention relates to a method and system for streaming channel data to apply non-linear beam forming. Systems and methods are provided for enhancing the spatial specificity and improving the efficient image acquisition speed by streaming the channel data to apply the non-linear beam forming. The method comprises generating a clutter filtered signal; delaying the clutter filtered signal to provide a delayed aligned clutter filtered signal; calculating the coherence of the delayed aligned clutter filtered signal; and non-linearly combining the coherency of the delayed aligned clutter filtered signal and the delayed aligned clutter filtered signal across each transducer element at one or more depths to generate at least one beam forming signal at the one or more depths for each received set of echo signals in the sequence of echo signals. The method includes calculating and presenting measurements for the one or more depths based on the at least one beam formed signal of each received echo signal group in the sequence of echo signals at the one or more depths.

Description

technical field [0001] Certain embodiments relate to ultrasound imaging. More specifically, certain embodiments enhance spatial specificity and increase effective image acquisition speed by performing stream processing on channel data to apply nonlinear beamforming. Background technique [0002] Ultrasound imaging is a medical imaging technique used to image organs and soft tissues in the human body. Ultrasound imaging uses real-time, non-invasive, high-frequency sound waves to produce two-dimensional (2D) images and / or three-dimensional (3D) images. [0003] Doppler ultrasound imaging uses reflected sound waves to visualize blood flow through blood vessels. Doppler ultrasound can help doctors evaluate blood flow through major arteries and veins, such as those in the arms, legs, and neck. Doppler ultrasound images can show blocked or reduced blood flow through narrowed areas of the main arteries in the neck that can lead to a stroke, and can show veins in the legs that ca...
