This study introduces a low-cost system for reconstructing 3D ultrasound images. The developed processing board enables high-resolution cross-section visualization from volumetric data, enhancing diagnostic capabilities.

Area of Science:

  • Medical Imaging
  • Biomedical Engineering
  • Signal Processing

Background:

  • Three-dimensional (3D) echography offers powerful diagnostic capabilities.
  • Reconstructing cross-sections from 3D ultrasound data is crucial for medical diagnosis.
  • Existing systems may be costly or complex to integrate.

Purpose of the Study:

  • To develop a low-cost processing board for reconstructing arbitrary cross-sections from 3D echographic scanners.
  • To integrate this system into stand-alone echographs for enhanced diagnostic utility.
  • To achieve high-resolution cross-section reconstruction at a practical frame rate.

Main Methods:

  • A processing board based on three pipelined Digital Signal Processing (DSP) devices was designed.
  • The system processes volumetric data acquired with a commercial echograph using a synchronized rotating probe and ECG signal.

  • The reconstruction algorithm was implemented on the processing unit.

    • Main Results:

    • The system reconstructs high-resolution cross-sections at one frame per second.
    • A time lag of approximately 60 seconds was observed due to the 3D acquisition process.
    • The resolution of the reconstruction algorithm was validated using both synthetic and experimental phantom data.

    Conclusions:

    • The developed low-cost processing board effectively reconstructs high-resolution cross-sections from 3D ultrasound data.
    • The system demonstrates potential for integration into existing echographs, improving diagnostic capabilities.
    • Further optimization may reduce acquisition time lag for real-time applications.
