This study characterizes the 3D structure of ultrasound speckle, revealing distinct, bright peaks. These measured speckle peaks are wider than previously predicted, offering new insights into diagnostic imaging noise.

Area of Science:

  • Medical Imaging
  • Acoustics
  • Ultrasound Technology

Background:

  • Ultrasound speckle is traditionally viewed as a noise source in diagnostic imaging.
  • Characterizing the 3D acoustical speckle pattern is crucial for advanced applications like 3D imaging and flow detection.

Purpose of the Study:

  • To characterize the three-dimensional (3D) acoustical speckle pattern in ultrasound imaging.
  • To physically measure the structure and dimensions of bright spots within the speckle pattern.

Main Methods:

  • Acquired ultrasound radio-frequency (rf) backscatter signals from a volume scattering phantom using an automated 3D translation stage.
  • Processed data offline to locate and measure envelope-detected speckle peaks (local maxima).

Main Results:

Related Experiment Videos

  • Identified a distinctive 3D structure within ultrasound speckle, enabling the location and measurement of peaks.
  • Observed that speckle peaks are brighter than the mean speckle brightness and uniformly distributed.
  • Measured speckle peak lateral breadth as over twice the width predicted by prior theoretical models.

Conclusions:

  • Ultrasound speckle exhibits a measurable 3D structure with bright, uniformly distributed peaks.
  • The physical measurement of speckle peak breadth significantly exceeds previous theoretical predictions.
  • This research provides a foundation for understanding and potentially mitigating speckle noise in advanced ultrasound imaging.
