Coherence-based ultrasonic imaging method

Value Proposition

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.

Technology

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.

Advantages

  • Superior contrast-to-noise ration
  • High image quality with increasing noise
  • High contrast for anechoic tissues / regions
(a) In vivo B-mode image of a cyst at 1.5 cm depth in a human thyroid. SLSC images of the thyroid formed with (b) Q=10.4% (c) Q=20.8%, and (d) Q=31.2%. (e) A spatialcompounded image of the thyroid. The SLSC images show improved CNR of the cyst and improved SNR of the thyroid tissue compared to the B-mode and spatial-compounded images. The SLSC images also show improved resolution compared to the spatialcompounded image.
