Area of Science:

  • Biophysics
  • Medical Imaging
  • Ultrasound Technology

Background:

  • Acoustoelectric (AE) imaging offers high spatial and temporal resolution for visualizing current source density (CSD) in biological systems.
  • Conventional AE imaging methods suffer from low signal-to-noise ratio (SNR) and frame rates due to limitations in focused-beam scanning.

Purpose of the Study:

  • To introduce and validate Hadamard synthetic beamforming (HSB) for ultrafast AE imaging.
  • To overcome the trade-offs between field of view (FOV) and frame rate in conventional AE imaging.

Main Methods:

  • Implementation of HSB using 16 transmit events per frame for spatial encoding.
  • Utilized a 1.5D transducer array at 0.6 MHz center frequency for imaging current sources in a bio-mimicking phantom.
  • Real-time imaging at a frame rate of 500 Hz.

Main Results:

  • HSB achieved reconstructions limited by transducer geometry, enabling high frame rates.
  • Demonstrated an approximate 5 dB SNR improvement over conventional focused-beam scanning.
  • HSB provided comparable spatial resolution with fewer artifacts and improved image quality for distributed sources.

Conclusions:

  • HSB is a practical and robust solution for achieving ultrafast AE imaging.
  • This method significantly enhances SNR and frame rates for bioelectric current imaging.
  • HSB offers improved image quality for dynamic and distributed biological current sources.
