Systems, methods, and / or computer readable media for adaptive spatial compounding in ultrasound

By adaptively spatially compounding ultrasound signals at different sound wave action angles and combining signal-to-noise ratio and speckle analysis, a clear composite image is generated, which solves the problems of image blur and reduced contrast in existing technologies and achieves improved needle visualization and image quality.

AI Technical Summary

Technical Problem

Spatial compounding methods in existing ultrasound imaging result in image blurring, reduced contrast, and decreased needle visibility, and existing speckle removal methods are unable to effectively improve image quality without activating the needle enhancement mode.

Method used

Adaptive spatial compounding method is used to transmit and receive ultrasonic signals at different sound wave action angles, and combined with signal-to-noise ratio and speckle analysis, the data frames are adaptively compounded to generate clear composite images.

Benefits of technology

Without activating needle enhancement mode and without losing image quality, it enhances needle visualization, improves image contrast, maintains clear vessel walls and organ boundaries, reduces noise, and improves image quality.

Abstract

An ultrasound imaging system (302) includes a transducer array configured to transmit a plurality of ultrasound signals, each at a different sonication angle, receive an echo signal for each ultrasound signal of the plurality of ultrasound signals, and transmit the echo signal to the transducer array. And generating an electrical signal indicative of each of the echo signals. A beamformer (329) is configured to beamform the electrical signal and generate a radio frequency (RF) signal for each of the different acoustic wave action angles. An envelope detector (604) is configured to detect an envelope of each of the RF signals for each of the different acoustic wave action angles. A compressor (606) is configured to compress each of the envelopes for each of the different acoustic wave action angles to produce a data frame. A recombiner (326) is configured to adaptively recombine the data frames for each of the different acoustic action angles to generate a composite image. A display (330) is configured to display the composite image.
