Area of Science:

  • Medical Imaging
  • Ultrasound Technology
  • Signal Processing

Background:

  • Conventional ultrasound imaging faces limitations in lateral resolution and depth independence.
  • Synthetic aperture beamforming techniques aim to overcome these limitations but often require complex systems and RF-data storage.

Purpose of the Study:

  • To introduce and evaluate Synthetic Aperture Sequential Beamforming (SASB), a novel technique for ultrasound imaging.
  • To improve lateral resolution and achieve depth-independent resolution compared to conventional methods.

Main Methods:

  • SASB employs a two-stage beamforming process using virtual sources and receivers to create a virtual array.
  • The first stage constructs B-mode image lines, while the second stage uses these lines with delay and sum beamforming on the virtual array.
  • The method was validated through simulations (Field II) and off-line processing of commercial scanner data.

Main Results:

  • SASB demonstrated a significant improvement in lateral resolution (FWHM improvement of at least 2x, -40dB improvement of at least 3x) compared to conventional dynamic receive focusing (DRF).
  • SASB achieved nearly constant lateral resolution across depth, unlike DRF where resolution degrades with range.
  • An estimated improvement in Signal-to-Noise Ratio (SNR) of up to 8dB at 80mm depth was observed with SASB over DRF.

Conclusions:

  • SASB is a viable technique for enhancing lateral resolution and depth independence in ultrasound imaging.
  • The method offers advantages over conventional DRF, particularly in resolution consistency and SNR.
  • SASB provides a pathway to improved ultrasound image quality with potentially reduced system complexity.
