Area of Science:

  • Medical Imaging
  • Ultrasound Technology
  • Minimally Invasive Surgery

Background:

  • 2D array ultrasound transducers have been previously developed for various real-time 3D imaging applications.
  • These applications include transthoracic imaging, intracardiac echocardiography (ICE), intravascular ultrasound (IVUS), and transesophageal echocardiography (TEE).

Purpose of the Study:

  • To develop and characterize novel 2D array ultrasound transducers specifically for real-time 3D laparoscopic ultrasonography (3D LUS).
  • To evaluate the feasibility of using these transducers for in vivo imaging during minimally invasive procedures.

Main Methods:

  • Fabrication of two distinct 2D array transducers: a 5 MHz (11x19 array) and a 7 MHz (36x36 array).
  • Characterization of transducer properties including element count, aperture size, center frequency, bandwidth, and insertion loss.

  • In vivo imaging experiments conducted on canine hearts using both transducers for cardiac visualization.

    • Main Results:

    • The 5 MHz transducer (4.5 MHz center frequency) produced real-time 3D images of canine hearts for cardiac function monitoring.
    • The 7 MHz transducer (7.2 MHz center frequency) generated real-time 3D rendered images of pulmonary veins, valuable for atrial fibrillation catheter ablation guidance.
    • Both transducers demonstrated suitable performance characteristics for their intended surgical applications.

    Conclusions:

    • The developed 2D array transducers are suitable for real-time 3D laparoscopic ultrasonography.
    • These transducers offer potential for enhanced visualization and guidance during minimally invasive cardiac procedures.
    • Further application in guiding cardiac ablation catheters for atrial fibrillation treatment is anticipated.
