Area of Science:

  • Physics
  • Medical Imaging
  • Acoustics

Background:

  • Diffraction tomography offers a non-invasive imaging approach.
  • Ultrasound tomography utilizes sound wave propagation for imaging.
  • Filtered backpropagation is a key algorithm in tomographic reconstruction.

Purpose of the Study:

  • To experimentally evaluate the performance of the filtered backpropagation algorithm in ultrasound tomography.
  • To assess the accuracy of structural and velocity reconstructions using this method.
  • To determine the suitability of ultrasound tomography for medical imaging.

Main Methods:

  • An experimental setup was created using a water tank with a plane wave source and a scanning hydrophone.
  • Cylindrical objects made of acrylic and silicone rubber were used as test samples.

Related Experiment Videos

  • Diffraction tomography principles were applied to reconstruct images from measured ultrasound data.

    • Main Results:

    • The filtered backpropagation algorithm successfully reconstructed the structure and position of the test objects.
    • Accurate velocity reconstruction was achieved, particularly when the velocity contrast was not substantial.
    • Reconstructions demonstrated good fidelity to the actual object geometries and properties.

    Conclusions:

    • The experimental results confirm the effectiveness of filtered backpropagation for ultrasound tomography.
    • The method's ability to accurately image structure makes it highly suitable for medical applications, given the small velocity variations in biological tissues.
