Coherence-based ultrasonic imaging method
In ultrasound, clutter that originates from acoustic interactions with surrounding tissues presents a significant challenge in numerous high-noise imaging environments, including vascular, cardiac, abdominal, and breast imaging. Thus, there is a need for better ultrasonic imaging methods to tackle poor image quality.
The inventors have developed a method of enhancing ultrasound image. The method utilizes the short lags of the spatial coherence function of the backscattered echoes. The in vivo application of short-lag spatial coherence function to human thyroid tissue demonstrated superior signal-to-noise ratio and contrast-to-noise ratio.
- Superior contrast-to-noise ration
- High image quality with increasing noise
- High contrast for anechoic tissues / regions
